I bought a Canon RP which came with a 24-105mm zoom. I think it was CAD 1000 a couple of years ago, but it looks like that has inflated to around double now.
I have an RP and it's great, but I still reach for my M50 slightly more often, being a fair bit smaller with the 22mm ef-m on it and maybe more familiarity with it by me.
It depends on your budget and interests. In terms of sensor size, Micro Four Thirds (from Olympus and Panasonic) is generally the most affordable, but it comes with a smaller sensor. APS-C offers a middle ground, while Full Frame is the most popular and typically delivers the best image quality.
Personally, I use Sony APS-C the most because of its smaller size, lighter weight, and more affordable lenses. Among APS-C systems, Sony and Fuji offer the widest lens selection. Fuji gear tends to be overpriced now, but it does have a stylish look.
Micro Four Thirds lenses are usually cheaper and more lightweight.
If you're shooting fast-moving subjects like birds or Formula 1 racing, Canon and Nikon are the most popular choices. They offer a wide range high performance lenses designed for demanding situations.
