You are being a plum – buying a bike that’s far too small for you. While it maybe a Santa Cruz it’s quite old vs your shiny new Bird.
Ett means whilst it maybe fine sat down, when you stand up it’s going to be so short it’s going to be attempting to throw you over the handlebars. Even with the standard 60mm stem.
What you should have done was buy the ML Aether 7 with the 479mm reach rather than the large.
Bearing in mind I’m 5’9 with long legs / short arms I wouldn’t want to go shorter than the 457mm reach I have on my medium Aether. Given your 3 inches taller than me I’d think my bike would be a bit small for you and the reach is considerably longer than that Bronson. If I were you I’d be looking at a reach between 460mm at the minimum and say 480 if you found the Aether in large too long.
Also if you’re considering going longer travel again I think you’d find an ML Bird Aeris 145 / 145LT / AM160 would be compatible with all your parts and would be a straight swap / not that expensive to buy – particularly the 145 / LT.
Edit – another option might be an airdrop Edit – I think the v2 was boost.
