It really depends on the use case, if it's going to be normal desktop type use with short bursts of high processor activity it will probably be fine with passive cooling. If you're planning to do hours of continuous processing (compiling big software on all 4 cores, etc) then you'll want to use some kind of a fan.
I pretend to use the Rpi4 4GB as a desktop computer. I tried to do it with the Rpi3b+ but it was a little not enough powerfull. Rpi4 4GB seems to be good enough, but in some causes, like youtube, it seems it doesn't act very smootlhy, so goving that extra 250Mhz and maybe some more GPU should help a little.

You want quiet and you want to preserve the warranty, and these are both at odds with overclocking.
If you *do* need that little performance bump, or if you just want to overclock for fun, I'd just make sure that you have good air flow over the sink. If testing shows that your Pi is averaging more than around 55C, use a larger sink.
Well, it seems if you respect those 2 details the warranty stays steady. Let's see how good/big is the heatsink it comes with the pack I ordered

Overclocking capability varies from individual chip to individual chip. You cannot rely on someone else's overclocking experience to be the same as yours.
The default settings are what all the SoCs are guaranteed to run stably at. If all the chips would work OK at higher settings, those higher settings would have been chosen as the defaults.
Anyway, other people experiences gives you a general idea of the possibilites, otherwise there would not be so many web pages showing benchmark results and comparisions about every SoC on the market
