Recommended VPS Setup for FluentCommunity + FluentCRM + WooCommerce?

I'm setting up a new WordPress site that will include FluentCRM, WooCommerce, and FluentCommunity — all in a single installation.

The goal is to ensure good performance and stability, especially for logged-in users in the community. I’ll use Redis, object caching, and maybe a CDN, but I’d really appreciate input from people already running similar setups.

Here are some specific questions:

1. What server or VPS specs are you using?
   (RAM, CPU, VPS provider, etc.)
2. Do you use any caching plugin?
   If yes, which one?
3. Do you enable page caching for logged-in users?
   Does that affect FluentCommunity in any way, or is it safe since the community runs as a separate SPA?
4. Are you using a CDN?
   If yes, which one? Do you recommend it for FluentCommunity? Have you seen any real performance benefits?

Would love to hear your thoughts too, Shahjahan Jewel, especially regarding caching and CDN — does it impact FluentCommunity much?

Thanks in advance!
