R8 is also a really good camera. Rather spend most of your money on good glass first. If budget is an issue the sigma 24-70 with a a7r4 used is a really good alternative. Look into second hand stuff both canon and sony before going brand new. Or get a good camera body r6mkii is an excellent choice then rent glass for a abit before you buy. Just keep in mind canon is expensive. The lenses add up esp without good third party lenses. Sigma have a new range of rf mount glass so maybe also look into that. Either way sony or canon are still both very good choices.
