The following are the Canon EOS RF mirrorless cameras that have been reviewed (click on the linked camera names below to be taken to the review):
So what would Thom get? The RP was a bare bones, entry camera. You bought it because of price. The R8 is the new entry level RF camera, and it's quite good for the price and a better choice for entry level in almost every way.
The R1 or R3 are certainly excellent choices for those looking for a fast frame rate flagship mirrorless camera akin to the 1DX DSLR, but I don't regard either as a more general camera due to the lower pixel count, among other things.
The most well-rounded of the full frame Canon cameras is probably the R6 Mark II, which brings the best of Canon's DSLR world into the mirrorless realm pretty much intact, while adding some mirrorless-only aspects. The R5 Mark II is the top end if you need the pixels, but the R6 Mark II is the camera most should be looking at.
Finally, with RF-S now a thing, the R10 (basically a mirrorless Kiss/Rebel) and R7 (somewhere between the 90D and 7D II DSLRs) are well worth looking at. The R7, in particular, is a solid camera capable of most everything most people would need. I'd tend to avoid the R50 and R100, as they are stripped of features.
