Is it possible to create a style in Word that changes only font and font size?

[Carlisle R.]

I am losing my sanity, I can't seem to be able to do what the title asks for the life of me, and I am wondering if it even is possible.

Here's the thing, I am writing a document that will have little pieces of code here and there, from single words to several sentences, so I wanted those to be in a monospaced font. Because they may end up being a lot, I thought creating a style for it would be good, so I created a new one based on the normal one, in the dialog I changed the font to be Cascadia Code and the size to be a little bit less, I didn't touch any of the other settings.

The first thing I tried to apply it to was a whole line inside of a bullet-point list, the end result was: bullet point deleted, and any styling removed.

Became:

After searching the Internet, turns out what I needed to do was to create a style with the type set to Character, but trying to modify the one I created shows that option greyed out:

So, I deleted that style, which, in itself was also not straightforward. The option to "Remove from Style Gallery" doesn't delete it, I had to first open the style manager dialog by clicking the little arrow bottom right of the style section the ribbon has, and only then it can be deleted, otherwise it is just hidden (I learned when I tried to create another one with the same name).

Anyway, creating a new style from that management dialog allowed me to create one that is Character typed, but it also doesn't do what I expected. The bullet point is now preserved, but any other styling is removed, the text was bold and green before and after applying the style it is black and not bold:

Also, note how the character being used for the bullet point (Word default, I still need to change it to something nicer) seems to have changed font as well. What is this?! It feels like Word is working against me! I know I don't use this program daily and my knowledge is rather limited, but damn, it is frustrating. Already when I selected those lines and changed the color to green I had to be careful not to select the whole line, or Word would change the bullet point color as well.

Font color is "Automatic" by default in the styles I created:

And in the Format -> Font dialog, it shows up as "No Color" instead, I tried changing it to "Automatic" as well, in case "No Color" meant removing it, to no avail, the end result is still the same.

I just wanted a way to have all code segments throughout the document use a common format, it would be tedious to change it all manually, and for any further change I'd have to go through it all every time instead of just editing the style which would be applied to all instances of it (I hope).

I am not using my computer at the moment, and I don't have enough privileges to tweak Office installation in case there is something extra that needs to be installed, it is used with a subscription, so it ought to be the current version of it.
