are you talking only about changes in the map view? if so, i think there have been a lot of suggestions for Explore page updates, including more dynamic scaling (i would assume mostly for mobile, but which could apply to large or wide monitors, too). see: https://forum.inaturalist.org/t/ideas-for-a-revamped-explore-observations-search-page/8439. this kind of limited request might go best within that larger thread.
(it may be worth noting that below the buttons to zoom in/out and to find your current location, there’s a button to view the map in full screen, which might be the actual best solution to view the map on a large or wide screen.)
if you’re talking about making the whole website more dynamic for large or wide monitors, then you probably should make a case for such changes on other pages. small screens are less niche than large / wide screens, and past requests for small-screen-friendly designs haven’t gone very far: https://forum.inaturalist.org/t/mobile-friendly-website-responsive/1224.
