Consider trying ZGC first. The main selling point is low worst case pause time. I've seen some tests where P99.9 pause time was less than 5ms, vs several hundred for older collectors.
In my limited tests I never saw a GC pause over 5ms. I was basically hammering a Spring Boot application with HTTP load tester.
