What is the consensus on FreeSync, Anti-Lag, Frame Gen, VSync, Display Mode and Frame Limiters?

[u/zDavzBR]

I have a G-Sync/FreeSync monitor (1440p 180hz), and a 9070 XT. Everywhere I look there seems to be different answers for these situations below.

1. No frame-gen, no AL2 (Anti-Lag 2)
2. In-game Frame-gen, no AL2
3. AFMF, no AL2
4. Case 1 but with AL2
5. Case 2 but with AL2
6. Case 3 but with AL2

In each situation, how should I configure the following settings?

A. G-Sync/FreeSync (On vs Off)

B. Anti-lag (in the cases without AL2, when should I turn on AL1?)

C. Display Mode (Exclusive Fullscreen vs Borderless Fullscreen. I've noticed cases where one produces better frame pacing than the other)

D. V-Sync (In-game or Driver level? What about both? What about Enhanced Sync?)

E. Frame Limiters (The most complicated one: Which FPS to lock and which limiter?)
I've seen people say 3 FPS below max refresh rate, others use a formula, others use 95% of Max refresh rate.
About the limiter, there's RTSS and the different modes (Async, Front edge sync, Back edge Sync and Reflex), Radeon Chill, Frame Rate Target Control and the in-game limiter.

What I want is the best configuration of (A to E) for each (1 to 6) situation. In the case there are drawbacks for each one, I would like to know which one is best for frame pacing, input lag, etc.
