You don’t need to speak much Thai if you live in Bangkok, Chiang Mai, or the more popular beach resort cities. You can get by with no Thai at all unless you intend to live in rural Thailand.

Thailand does not have a remote worker visa like some European countries do. The requirements for the DTV (erroneously called a digital nomad visa) look hard to satisfy, and then you only get to stay 180 days in a year.

Thailand does offer other visas you can research. Digital nomads in Thailand typically come and go on tourist visas. Look into Thailand Privilege (formerly Thailand Elite) for a decent visa you can just pay for.

Honestly without a college degree and a high income you can document, combined with a passport that I guess limits your options, you will have to put significant effort into moving anywhere long-term. Look into Indonesia and Malaysia, both friendly to immigrants and nomads, cheap, safe, if not democratic in the American/western European sense.

If you're looking for a beautiful place to go outside, Svalbard is not it lol.

Thailand is awesome, however they're not like many other well developed places where English is important to them. They are proud of their language and you'll need to learn it to get on. It's a shame because you speak English perfectly.

If you want something that your English can be a skill that you can put to use, Europe and the English speaking countries have pretty strict rules (for legal immigrants). You can get work as an English teacher in Korea or Japan since you're so good at it, especially if you learned it as a second language you're more familiar with the formal structure of the language than a native speaker because you had to learn them from scratch. Not quite tech work, but they're reasonably nice places. They're a little racist but they see nothing wrong with it, and their target of dislike is probably not you so you probably won't see much of that. And, their racism isn't usually hateful, they just stereotype and stare and ask inappropriate questions mostly.

Latin America... you'll need to learn Spanish. Most of the place is unbelievably beautiful, but there's some corruption and crime. The Caribbean, it's also beautiful, and many places have English as the primary language, but again, similar problems to Latin America.

The pacific islands are nice, most of them are full of English speakers, but many of the islands are UK or US territories and you'll have a hard time going for the same reason you'd have a hard time going to the US or UK. Also, some places like american Samoa, they have weird laws about land ownership, and interestingly those from there have US passports but are not US citizens. There are many that aren't US territories but that are guaranteed military protection and use the US dollar. Tons of great places there if you do your research.

As far as Mexico, many places on the Baja peninsula are relatively crime free, as developed as any US town, many people speak English there because of a history of tourism from the US state of California. Maybe worth checking out. Mexican passport holders can travel to more countries visa free than any other country's passport, and in many other places, get a visa relatively easily, so it might be a great idea to get one if you want access to much of the world.
