Some things may not be doable with Covid but I would recommend:
Newport - mansions, The Cliff Walk, 7 mile drive, Thames St
Providence - WaterFire, good restaurants, tour the East Side, Roger Williams Park ( I love the greenhouses).
Great towns to explore: Westerly, Narragansett, Wickford Village, Jamestown.
I have stayed at Whispering Pines Campground.
If you're in RI you can easily tour Eastern CT (Mystic Seaport) and Southeastern MA (Battleship Cove in Fall River, Whaling Museum in New Bedford)
