Ok, casting gear sounds good. You don't need a light wire hook in that case.
With brush and wood in the mix, I would actually prefer a somewhat shorter shank hook and fish more vertically (rather than drag it; use the rod tip to guide the jig in and around them).
With the depths you plan on fishing, I'd start with a 1/2 oz. (up to 2' or *twenty* feet??).
While I do prefer football heads in rocks, fishing them in grass is not easy. Agree that the arkie head is a good all-around choice. In fact, I'd recommend a brush head if you're casting <50' or so. Most brush head jigs also have the hook angle optimized for short distance fishing.
You'll lose jigs from the bank. I lose them from the kayak/ boat often enough.
If you want to go the arkie head jig route, go to walmart and buy some "arkie brand rattle band bass jig". Costs ~$1 each out here anyway. Trim the weedguard a bit; that'll make it stiffer. Also superglue the weedguard in. I've had them occasionally fall apart after a few hours (if the jig lasted that long).
Get some mono or a ziptie and tie the skirt; they'll fall apart otherwise. I usually do a lot more mods. But don't worry about that. I like these for good all-around jigs at any price (after the mods).
Pair with your favorite trailer. GYCB 5" DT grubs are a good all-around choice. $5 for a pack of 20 and they catch fish. I also like rage craws (the regular size, not the baby, not the lobster), rage menace, beavers when it's cold, keitech crazy flappers, and a few others. Haven't met a trailer that didn't catch fish. Pick one you're confident in.
A more convenient option might be a swing style jig with no skirt. Strike king structure head in 3/8 oz. Do not buy the football head swing jigs for this purpose. Pair with your favorite plastic, and you can pitch flip skip and cast that and fish it exactly like a skirted jig.
Good luck.
