I want to do all the following by jQuery and my HTML as well as CSS is below.

The paragraphs start hidden.
The paragraphs show and hide when their headings are clicked.
This process should take 3 seconds.
Mousing over the paragraph will reverse the colours of the text and background.
Mousing out will switch the colours back to their original values

jQuery(document).ready(function () {
    jQuery('.contentBox').css('display', 'none');//SELECT BY CLASS
$('h2').click(function(){
    $(this).next('p').slideToggle();
});
});

body {
    background: tan;
}

h1 {
    margin-left: 150px;
}

h2 {
    margin-bottom: 2px;
    padding: 3px 0 2px 25px;
    background: #D99E50;
}

p {
    margin-top: 0;
    padding-top: 0;
}

#mainContain {
    background: #523C1E;
    width: 80%;
    margin: 0 auto;
    padding: 30px 0;
}

.contentBox {
    background: #524737;
    /*Paragraph background color*/
    padding: 15px;
    color: #FFE5C3;
    /*Paragraph font colour*/
}

/*Text Panel Styling*/
.panelContainer {
    background: #523C1E;
    width: 80%;
    margin: 0 auto;
}

To have the slide toggle animation take 3 seconds provide an argument to slideToggle() which is the number of milliseconds the animation should take. In this case, 3000, but note that this is very slow. I’d suggest that you shouldn’t make effects last longer than around 500ms.

To have the p styling change on mouse hover, use the :hover pseudo selector in your CSS.

In addition, it’s better practice to always use CSS to hide content which should not be visible when the page loads. This is in order to avoid a FOUC, which can happen due to JS running after the DOM has fully loaded and been rendered to the screen.

jQuery($ => {
  $('h2').on('click', e => $(e.target).next('p').slideToggle(3000));
});

body {
  background: tan;
}

h1 {
  margin-left: 150px;
}

h2 {
  margin-bottom: 2px;
  padding: 3px 0 2px 25px;
  background: #D99E50;
}

p {
  margin-top: 0;
  padding-top: 0;
}

#mainContain {
  background: #523C1E;
  width: 80%;
  margin: 0 auto;
  padding: 30px 0;
}

.contentBox {
  display: none; 
  background: #524737;
  padding: 15px;
  color: #FFE5C3;
}
.contentBox:hover {
  background: #FFE5C3;
  color: #524737;
}

.panelContainer {
  background: #523C1E;

While you seem to have achieved points 1 and 2 already, the easiest way to achieve points 3-5 is as follows, with explanatory code in the comments:

jQuery(document).ready(function() {
  jQuery('.contentBox').css('display', 'none');
  $('h2').click(function() {
    $(this).next('p')
      // to address point 3: here we supply a 'duration' argument
      // of 3000; this is in milliseconds, so this is equal to 3 seconds:
      .slideToggle(3000);
  });
});

// caching the values as CSS custom properties
// you wish to use as the color, and background-
// color, of the p.contentBox elements:
:root {
  --color: #FFE5C3;
  --bgColor: #524737;
}

body {
  background: tan;
}

h1 {
  margin-left: 150px;
}

h2 {
  margin-bottom: 2px;
  padding: 3px 0 2px 25px;
  background: #D99E50;
}

p {
  margin-top: 0;
  padding-top: 0;
}

#mainContain {
  background: #523C1E;
  width: 80%;
  margin: 0 auto;
  padding: 30px 0;
}

.contentBox {
  /* to address point 5 (and point 4), here we set
     the default color of the element(s), using the
     CSS var() function to supply thevalue held in
     the named custom property: */
  background-color: var(--bgColor);
  /* And again: */
  color: var(--color);
  padding: 15px;
}

.contentBox:hover {
  /* for point 4: here we do the same, yet again, but
     reverse the properties, so the color is now set
     to the color of the '--bgColor' custom property: */
  color: var(--bgColor);
  /* ...and the background-color is set to the value
     of the '--color' custom property: */
  background-color: var(--color);
}

/*Text Panel Styling*/
.panelContainer {
  background: #523C1E;

JS Fiddle.

It’s worth noting that a 3000ms animation is slow, and may be perceived as a lack of responsiveness in your site. This may, or may not, be a problem for you but it’s worth testing with your users. My personal inclination is to animate for around 0.4s (400ms), but my use-cases may not reflect your own.

References:

CSS:
- :root.
- CSS custom properties.
- var().
jQuery:
- slideToggle().

Here is the solution based on your all requirements:

$(document).ready(function () {
  $(".contentBox").css("display","none");

  //click event
  $("h2").click(function () {
      $(this).next(".contentBox").slideToggle(3000);
  });

  //hover effect
  $(".contentBox").hover(
    function () {
      $(this).addClass("textHovered");
    },
    function () {
      $(this).removeClass("textHovered");
    }
  );
});

body {
  background: tan;
}

h1 {
  margin-left: 150px;
}

h2 {
  margin-bottom: 2px;
  padding: 3px 0 2px 25px;
  background: #D99E50;
}

p {
  margin-top: 0;
  padding-top: 0;
}

#mainContain {
  background: #523C1E;
  width: 80%;
  margin: 0 auto;

You can initially keep make paragraph hide by Hide() function in jquery and then by clicking on each heading use slidetoggle function for paragraph and use Next() to show paragraph of clicked heading.
to change background and font color, jusr use hover function and in that make background to font-color and vice versa.

For better interactivity if you wanted one paragraph to hide on click of another paragraph you can apply a slideUp to every paragraph and then open the required div.
```
    $('h2').click(function () {
        $('.contentBox').slideUp(3000);
        $(this).next('.contentBox').slideDown(3000);

    });
```

Not sure what is your error. I find an error when I Run code snippet:

Error: {
  "message": "Uncaught ReferenceError: jQuery is not defined",
  "filename": "https://stacksnippets.net/js",
  "lineno": 117,
  "colno": 9
}

If that is your issue, you can check the jquery files in your local or use:

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script>

To meet your request, you can try

jQuery(document).ready(function () { 
    $(".contentBox").hide();

    $("h2").click(function(){
        $(this).next(".contentBox").fadeToggle(3000);
    });

    $("p").hover(
        function(){
            $('p').css('background', '#FFE5C3');
            $('p').css('color', '#524737');
        },
        function(){
            $('p').css('background', '#FFE5C3');
            $('p').css('color', '#524737');
        }
    );
});
