I would pay for Cloudflare Workers Paid ($5) in a heartbeat and currently use the free version of cloudflare for all my DNS / Hosting etc. Where it does not meet my needs i have Dokpoly + Digital Ocean. I would use CloudFlare Containers. I currently pay for resend.com for all my email API needs.
The problem is that once you're on the paid plan, you're exposed to unlimited risk if your worker goes crazy due to a stupid code bug or if you're hacked. As a solo dev, it's a risk I simply cannot take; I could wake to a bankruptcy bill from Cloudflare. Even as a company, an employee could sign you up and your accounts team would have no idea of the risk.
I am using Supabase at the moment, and see they have a hard cap now. and so does Vercel after they had some nightmare stories of large bills in the past.
I am not sure why / what CloudFlare think about this - or simply dont care.
They are working on it

Side note: the bills from cloudflare are much lower than the ones from AWS/Vercel when there's a mistake. The most I saw passing by was 150€, with Vercel and AWS > 10 k.
100% agree. Spending limits for Workers would be a game changer.
There are many services I wanted to use Workers for but ended up with some self hosted service simply because I can't properly limit my monetary risk here.
