What’s your previous employment background & skillsets?
Some jobs/roles/industries are inherently more remote-friendly than others, such as:
- Computer programming & adjacent roles (look to Hackernews for that)
- Social media “influencers” of various types, but especially for video games
- Customer support (by email or phone)
- Writing (technical or creative) or copyediting
- Some forms of digital art (illustrations, games, animations)
- Digital marketing
- Telemarketing & cold-call sales positions, often commission-based
- Political outreach
- Sometimes maybe audiobook recording or voice acting for games, etc.
Basically, if the job itself is mostly done in front of a computer and isn’t particularly location-dependent or in need of much real-time collaboration with a team, it’s more likely to be available remotely.
However, unfortunately you kinda missed the boat on that
During COVID it was very common for many jobs across different sectors to have become fully-remote, but then as soon as it ended, companies started to slowly (and then quickly) roll that back. By now most of the remote jobs at big companies are gone, with the CEO class needing to restore control over their minions.
You can still find some here and there at scattered small-to-mid-sized businesses, but they’re much harder to come by and you’ll have a LOT of competition. Some % of the workforce got used to the perks of fully remote during COVID and are reluctant to give that up, even as employers try to drag them kicking and screaming back into the office 
For what it’s worth, I work a fully remote job (web development), which I got mostly from having contacts. My previous remote jobs were similar, either starting in the office at first (until I proved I could do the work) and/or being hired by word-of-mouth. (It’s ironic; I don’t really like working remotely and miss the office a lot… that’s offtopic though.)
Connections are everything, especially when your employer can’t oversee you face-to-face everyday. Is there anyone in your professional network who might be hiring?
All in all, it really depends on your skillset and who you know. You can browse jobs marketplaces for remote jobs, like Indeed (https://www.indeed.com/jobs?q=&l=remote), or look on LinkedIn (if you use that).
If you don’t have any significant professional experience in a desirable skill, you might be left with super-generic freelance jobs like at https://www.upwork.com/ or https://www.fiverr.com/ where you try to market yourself somehow (against hordes of others competing with you). At the very very low end there is still Amazon’s mechanical turk (https://www.mturk.com/), but that usually pays pennies to mere dollars per hour, not enough for even a minimum wage (in the US), much less anything approaching livable
Ultimately, fully-remote jobs often mean you’re competing against a global workforce… there are plenty of people from poorer countries who would gladly do an average American’s job for 10% of the wages and put in 2x the hours and never complain. And ageism is a thing, especially in many of the more modern fields
