1. Why do you still need to limit your FPS if Reflex does it automatically?
You don't "need" to, but if you want to use G-SYNC + V-SYNC + Reflex + an in-game or external FPS limit, you have to limit a few frames below the auto Reflex limit to override it.

2. For games like Overwatch, Apex or Battlefield, is it better to cap your FPS at 138 (I'm using a 144Hz monitor) or is it better to not cap it?
You mean G-SYNC + V-SYNC + 138 FPS vs. G-SYNC off + V-SYNC off + uncapped? If so, it's entirely subjective...
There's no "better" here in every respect; G-SYNC off uncapped can reduce average input lag over properly configured G-SYNC by a couple more ms (the reduction/advantage of which decreases the higher the max refresh rate) due to tearing, assuming 1) your framerate is at least 2x above your refresh rate, and 2) said framerate doesn't max out your GPU-usage (or you have Reflex on with uncapped G-SYNC/V-SYNC off).
However, on the flipside, G-SYNC + V-SYNC, within its range, eliminates tearing, and syncs the framerate to the refresh rate, making frame delivery smoother and more consistent at the cost of tearing removal, which prevents the framerate/frametime from exceeding the refresh rate.

3. In the Battle(non)sense video, he says that Nvidia Reflex is useless when doing G-Sync +V-Sync Nvidia + limit FPS. I didn't understand why. Don't you have to activate it in this case of configuration?
I don't specifically know what comment of his you're referring to, but I'd assume he means if you can sustain your FPS at your set limit with G-SYNC + V-SYNC, and your GPU isn't maxed at said framerate, Reflex can do nothing further to reduce render queue input lag unless your framerate drops below your limit (in which case it can be left on as a fallback).

In the case of competitive FPS, is it better to disable G-Sync and only use Reflex Boost without limiting my FPS?
Absolute lowest input lag will always be G-SYNC off + V-SYNC off + uncapped + GPU not maxed, but tearing/micro-stutter is the trade-off. Again, it's subjective; There's no one "right" answer between the two.

If I want to use G-Sync + V-Sync in addition to Reflex (in case Reflex remains useful), should I limit my FPS to 138 or not cap it?
Again, depends on if your FPS ever drops below your limit; if it does due to your GPU maxing out, use Reflex as a fallback, if it doesn't, Reflex won't do anything further to reduce input lag.
