Sony A7iv vs Nikon Z6iii vs Canon R6ii

Sony A7IV with Tamron 28-75mm F2.8 Di III VXD G2  vs Nikon Z6 III with Tamron 28-75mm F2.8 Di III VXD G2 vs Canon R6 II with Canon RF 28-70mm F2.8 IS STM 

I plan to do event photography (wedding, baptize, sweet 18, etc), concert photography (metal and jazz or more if I get gigs), street photography (night too), building photography (shooting pretty buildings in my city), artsy photography, photoshoots, product photography, business photography (restaurant, bar, hotel, etc). I also plan to maybe print some of my photos to sell them (not necessarily a huge print). Also I don't care about video at moment. AKA I want a really versatile photography camera

Another mention all of the bodies are the same price +/- but the Canon gives the RF 50mm F1.8 STM for free. On the lens, both the Tamroms for Nikon and Sony are the same price, the Canon lens is 600 more euros.

Sorry for the long text and if I offend someone with my question lol.

Thanks in advance!
