This sounds like a lot of the natural lakes around here also. The water is super clear and the grass grows deep. There is one lake around that the grass grows all the way out in ~25' of water and makes it a couple feet off the bottom there. Anything from 20' and shallower it tops out on the surface. On a separate note, that lake also gets big blobs of green algae which are incredibly annoying and what put me off fishing that lake.
Phish has you pretty well sorted and local knowledge always wins. I also love the early mornings and late evenings into the night this time of year. The bass are largely cruising the edges to eat. Then when the sun comes up and they just tuck back into the grass. Sometimes they just settled to the bottom, sometimes they bury back in. I think light levels, predation levels, and human presence are what drive those decision for the fish. Sounds like you're on a tougher lake with plenty of humans, so if you're not fishing on a wednesday after no one has fished it Tuesday or Monday then there's a good human presence to deal with.
I would still fish that grass . Start with a 3/8 but don't be afraid of a 1/2 or more. Beavers have been my go to for a general search bait in this scenario. Use your fish finder to mark the edge- start out deep where there isn't any and move in shallower until you see it starting to grow up off the bottom. Set a waypoint if you can, or make a mental note of how far you are from the surface grass. That's where you want to start. They will cruise or set up on the very outside edge where the grass stops at times and these are the easiest ones to catch. They are deeper and harder to fish (you have to have a mental picture of the bottom or FFS) but they are the fish that are actually eating. You can drag parallel to the edge to good effect. Just watch for a thermocline. Right now its at 15' around here and there's nothing below it.
If the fish aren't there, then move shallower and pitch to every little opening or pocket you can see. Use enough weight to get down to the bottom of it. Its mentally exhausting work to work a grassbed like that, but sometimes that's the only way to catch them.
