Help with hotel recommendations/planning for Italy honeymoon!

Hello! After a lot of consideration, we are thinking of doing Italy for 2 weeks, starting in Tuscany for 4-5 nights and spending the rest of the time around Amalfi Coast. We are mostly looking for a chill trip, but would love to sunbathe and swim, and also just walk around cities, shop, and eat lots of good food. We are open to suggestions on destinations in Italy as well, as I'm really overwhelmed and not sure the best choices (we aren't really interesting in historic sites or anything like that).

I think the room is super important when travelling and would like to feel some luxury and great views in wherever we go. We are aiming to spend $6000 (excluding flights), and I'm wondering if it's even possible to go somewhere more luxurious for that cost. My research so far hasn't felt hopeful. I obviously need enough money to eat out, and maybe do a couple of excursions like a boat tour or other things like that.

I'm looking at Airbnb's and hotels. I just want to make sure I can get around okay from them. I'm just super overwhelmed as I don't know Italy at all and there's so many areas and places to stay, and I don't know how much things end up costing out there. Any help would be appreciated, thank you!!
