I made a similar post in the EOS R forum, but I was recommended to make a post here to get more answers. As you know by the title I'm interested in starting macro photography with my R7, but I have a few questions first. My first question is what lens would be good for me?
Can you tell us more about you? Are you meticulous and precise, or an "on the fly" shooter? Do you work on tripods or handheld?
For the RF mount, I see only 1 macro lens that is within my budget of around $500 and that was the RF 85mm f/2. That only has a 0.5x magnification which I don't think would be best for what I plan on shooing (spiders, other insects, fungi, and plants).
Well, a 0.5x on a Canon APS-C fills the frame with a subject 30x45mm. How big are the spiders and insects in your area? What sort of fungis?
If you can get by with 0.5x, the Canon gives you IBIS, which might be handy for handheld insects.
Are there any good third-party options I could get, and use an ef to rf adapter?
My favorite approach is a radical departure from Person9's suggestion. I think his and my respective approaches are both valid and each have their own strengths.
When I have time for tripods and precision work, I like working on a bellows with enlarger lenses.
You can find a Canon Auto Bellows or a Nikon PB-4 or PB-6 used in the $50-100 range. (there's also a Nikon PB-3 and PB-5 that you want to avoid. The 4 and the 6 are the versatile ones). Those use the old Canon FD or Nikon F mounts, respectively. They're basically interchangeable, you can get all the adapters you need to use either for about the same price.
- An adapter for the R mount camera is about $25.
- For "forward mounting" lenses you need a M39 adapter. Around $20.
- For "reverse mounting" lenses you need a 55mm reverse mount for around $20 and a 40.5mm-55mm step up ring for another $10.
Then you need a couple of enlarger lenses, or a specialized macro lens. I recommend starting with enlarger lenses:
- 100mm f/5.6 EL-Nikkor, about $75 used. Can focus to infinity but isn't great, and will go up to about 2x magnification.
- 50mm f/2.8 EL-Nikkor, about $50 used. Goes from about 1.5x to 5x.
There are also more exotic "short mount macro lenses" you can put on a bellows. My goto is a 50mm f/2.8 Leitz (aka "Leica") Photar. Those tend to go anywhere from $200-500 though. If you can find a nice one at the low end of the range, you're really set for 1.5x to 5x.
The Canon 20mm f/3.5 will cover from around 4x-10x on a bellows and can typically be found from $150-250.
One of the advantages of the Canon Auto Bellows or Nikon PB-4 or PB-6 is that they have three sets of gearing: one that moves the lens in relation to the camera, one that moves the camera in relation to the lens, and one that moves the whole bellows assembly (camera + bellows + lens) together as one unit. This makes fine focusing easy, and shooting "stacks" of images for use with "focus stacking" programs like Zerene or Helicon relatively painless.
Allan Walls has some great blog posts and videos on enlarger lenses for macro.

My last question is how does an APS-C body perform in macro photography?
Very well. In many ways, even better than full frame.

The term "mirrorless" is totally obsolete. It's time we call out EVIL for what it is. (Or, if you can't handle "Electronic Viewfinder Interchangeable Lens" then Frenchify it and call it "LIVE" for "Lens Interchangeable, Viewfinder Electronic" or "Viseur électronique").
