Hello. I have two questions.
1. Which Os is better to use if CentOS 7-8 ceases support?
2. For example, the site runs on php 8. If after 1 year I do not pay for the Pro version, will the site continue to work without problems?

almalinux 8.9 is the recommended one NOT CENTOS

Please just pay the devs their bit of money for Pro. It is worth it for all they bring to the table -- a good value proposition. Otherwise, seek out a free panel like Webmin if that will meet your needs.

Interesting username...

1a) AlmaLinux 8.x is currently recommended.
2a) CWP does come in 2 version CWP Free, which does have some features disabled like PHP-FPM & limited Mod_Security, and CWPpro.
Either will work for what you mentioned.

But for US$1.49/month, CWPpro is defiantly worth it.

just purchase the cwp pro - with the extra features its 100% worth it and i mean $1.49 is not even a price of a coffee these days!
