I am currently renting the R7 in order to assess whether this is my next camera. It is fantastic. Various pros and cons are that it gives great image quality even at high ISO, despite having lots of pixels for a crop sensor. Blazing shutter speed, focus bracketing, profocus. And I'm sure it goes on.
There are some critiques you will find on YouTube about how its focus point will inexplicably drop off of its target when using it for birding. So in a burst of shots it will be focused on the eye of the target, then suddenly it will blip over to focus on something nearby. I don't do that photography, so I don't particularly care. It's a problem that several on YouTube bring up.
What I suggest that you do is rent the camera with an adapter and try it for what you do. The best price for that was at Lens Rentals, and you will have the option to just buy it-- sending back the empty case. The asking price for my copy is the best price I've seen for a used one, and my copy is in perfect shape.
One possible issue for me was that one feature is that you can look thru the viewfinder and meanwhile use your finger to control the focal point on the main screen. It was very glitchy for me, although it's possible I was not doing it right or the sensitivity was wrong. But you should try that yourself. If nothing else, you will definitely have fun playing with this camera, like I am. I am still not sure what I will do.

I had the 7D then the 7D MKii and now the R7. I will not go back to DSLR after having the mirrorless R7 because what you see is what you get. Plus, the focusing is so much faster with the R7.

A friend of mine had the 5D, latest mark whatever that is. He went on a photoshoot and was so disappointed because he had full frame and could not get the the better wildlife shots in the everglades that those with APS-C got. He purchased the Canon 7D MKii and uses his crop sensor camera over 90% of the time and lets his full frame camera sit.

I much prefer the crop sensor of the R7 mirrorless plus the extra features vs the DSLR.

You cannot go wrong with the R7.

I use the camera for nature and BIF. Before getting the R7, I used a 7DMKII for about 6 years. Picked the R7 mirrorless for eye detect, greater frame rate and the same auto-focusing systems as the R3. Married it with the RF 100-500 (have used the RF adapter with the EF100-400 LII and that works great as well). Becoming more efficient with the menu system of the R7 versus the button system of the 7d Mk11. The most difficult transition has been with the electronic viewfinder (EV). For very quick reaction shots, like catching a Virginia Rail running across a boardwalk, the time delay with the EV going active and getting the camera to eye level means you'll lose 50% of the shots compared to an optical viewfinder of the 7D. Still learning how to tweak the auto-focus system with custom settings. Agree with all the positives and I'm brute forcing my way through any EV issues. Staying with the R7 and RF100-500 as my walk along camera system for nature and BIF.
