I have a Pro Display XDR for working at home w/ a 16" MacBook Pro M1 Max. I use it with my personal MacBook Air M1, too. I like my spreadsheets for personal finance BIG.

It's not just the GPU that shares memory with the CPU. The "media engine" buffers are in there, too at 18 megabytes per frame for 4k reference pictures in the decoded picture buffer. The decoder, scaler, GPU, and DRAM are fast enough to have several tracks of 4k (which even the iPhone 11 & SE can shoot), so don't let RAM size be your limit. I'm happy to see a max of 24GB vs. the M1's 16GB.
