I am looking for a proxy server that can connect to many types of connections. It is also necessary that it has flexible tariff plans so that in the future, if necessary, I do not have to look for a proxy provider. What do you recommend?

It's cool that you pay attention to such criteria and are quite far-sighted. I can recommend proxy compass https://proxycompass.com/de/free-trial/, which supports many connection options, such as socks5 and HTTP. It also has a whole network of tariff plans that are quite flexible, so I can recommend trying a trial period and making a final choice.
