Yo, I’ve been down this rabbit hole too. Honestly, most of the proxies 100 google docs I found were trash. Ended up going with Bright Data (formerly Luminati). It’s paid, but their proxies are super reliable and fast.
If you’re on a budget, try ProxyNova. They’ve got a decent free tier, but the paid ones are way better.
