I tried to buy a phone supported by LineageOS. And I have to say, this is impossible, given the restrictions ("available now" and "costs less than 500 USD including shipping to the Philippines"). So I ended up with a Poco X4 Pro 5G and Pixel Experience as a custom ROM.
Yeah it can be quite limiting. Especially when you start looking for specific phone options. I have the older Pocophone F1 and it's great. Unfortunately can't buy it anymore anywhere.
