An aquatic research center. Have towers out of the lake hoisting up buildings in the sky, connected by bridges and halls. Glass, prismarine, and endstone and purpur, for best effect.
Alternatively, a mushroom farm. Get a silk touch shovel and rip up some podzol/mycelium or a silk touch pick and get nylium. Ruined portals tend to have these quite a lot and they sit around unused for me because I hate gold tools without mending.
