Highlight.io has documented getting logs from Render here https://www.highlight.io/docs/getting-started/backend-logging/hosting/render

I'm likely going to switch over to them for error tracking, so I've been keeping an eye on their updates.

Oh, no idea if this is feasible but I'd love to see it. We spend a lot of money on logrocket and, well, it technically works but it's pretty slow. I'd love to have something a little cheaper and built into render (and open source!)
