Where is the first country you want to visit? I haven't visited that many countries but I think that Fiji looks really cool! I saw it on Survivor and I love the sea, sand and beaches. I imagine there will also be lots of things there that look like the movie 'Moana'
I'd love to go to San Marino when this is all over
Also if your going to Fiji, I'd 100% reccomend checking out some of the other countries around it. Fiji is beautiful, but places like Tonga, Vanuatu and Micronesia are still very cultural and a bit more off the beaten track for tourists
