I'm not sure what lenses you have that will be applicable, but that could be a factor if you have some good EF lenses. As it turns out, in my case, I had been shooting Canon APS-C for years, and my "L" EF lenses were about 20 years old. I spent a lot and got all RF lenses (mostly "L," but I have some nice consumer lenses I like, particularly the RF100-400, RF16f2.8, and RF24-240).
Canon RF lenses are very good but more than a tad expensive. Sony has the advantage of licensing 3rd party lenses and has been around for many more years, so there are many more native lenses at a wider range (often lower) of prices. When comparing prices, you should map out what lenses you think you will likely get in the next few years.
There are a lot of pros and cons to each body, and I would suggest looking at multiple reviews. If you are going to shoot a video, the 4K capabilities are quite different.

I’m trying to decide which camera I should buy to upgrade my aging 6D from 10 years ago. I pretty much ruled out the Sony A7 IV as the R6 Mark II is a slightly better option in almost every way. However, at that price point, I could get a barely used A7R IV. Megapixels aren’t everything but 61 megapixels have appeal especially when cropping. I mostly do portraits, landscape, and wildlife. The R6 Mark II brings a lot to the table however, including much better autofocus and shutter speed for wildlife. Ultimately both would be fine but I’m having a hard time picking one. I would appreciate your thoughts on the matter.
