Also, since you are gonna be taking self portraits, second most important aspect is Auto Focus. (First is lens but debatable) most of old Dslr cameras have very primitive Auto Foucs and best in the game is Sony for AF. When I bought my camera last year, I made a very detailed research and tried many cameras in the market. Most of them are not smart enough to recognize your face when you wear sunglasses but Sony(latest ones for apcs a6400,6100,6600 and any ff released after a7iii) so great that it immediately recognizes yourface even if you wear a mask.
Last but not least also think about second hand market in case if you wanna sell your gear in the future. Fujifilm is very bad in that sense but sony again dont lose much value.
