I would stick with a prime. You may think you’ll use the zoom, but I have a feeling you’ll probably end up finding a distance you are comfortable with and shooting from that, instead of adjusting your zoom with each shot.
Since you’ll be shooting low light and you aren’t confident in the steadiness of your hands, you’ll definitely want some form of image stabilization, otherwise you will miss out on shots. Really, your best friend is going to be flash. I’d recommend getting a speed light to help with AF and lighting, so you can get those crisp low iso shots that you will want. If you aren’t comfortable with an external flash, then I’d say to rent it ahead of time and do some work before hand to learn the ins and outs.
Out of the lenses you’ve posted, I’d recommend the 24mm 1.8 with image stabilization. Though I would aim for something closer to 35-50mm focal length. Remember, you are running a crop sensor, so all of your focal lengths will be might shorter than advertised. A 50 will act like a 35 and a 24 will be something like a 15-18. I’m a Nikon guy, so I don’t know if that knowledge translates directly to Canon, but I don’t think there is too much of a difference. I had the math backwards for whatever reason, but I stand by my advice.
Agree on using a speedlight, but if flash is in the picture stabilization won’t be as necessary. I wrote up a fairly similar reply on the .world version of this post.
I have experience with a 24mm prime and I was never truly satistied with landscape/scenery pictures because it was too narrow for them, and neither with portrait pictures because it was too wide. Of course, this is with it in my hands, there certainly are people out there who can use it better than I do.
I’m using a RF 15-30 f/4.5-6.3 when it’s bright outside and I like it a lot, I like the flexibility it gives me, that is why I’m tempted by the absolute brightness of the primes I’ve found, but also I’m tempted by the flexibility those zooms give me.
I don’t think I’ll be using an external flash because I fear my setup will become too cumbersome to carry around, and I prefer the feel I get from pictures when there is no flash involved :(
