Aside from testing multiple browsers, that'd make me think you want Chrome or Firefox primarily, if any difference at all they probably have best/most tooling?

All of the Chrome-clones (Edge, Vivaldi, Opera, Arc, etc) have identical dev tooling and extension support because they’re all just Chrome with mostly-surface-level tweaks applied.

I didn't realise Edge was such. Why would it make any significant difference to energy usage then?

"Identical extension support" is untrue: Brave is a Chrome clone, and it intends to keep supporting manifest v2.
