OK, so I have to buy a level shiter.
Which one would you recommend me to buy in terms of reliability and ease of use?
Check the link I gave you earlier.
I’m personally partial to anything with the 74AHCT/74HCTxxx chips, single 5V supply and they work well.
Make sure you don’t leave inputs you’re not using as “floating”, they must be pulled either High or Low.
And don’t forget the 100nF power supply decoupling capacitor near the power pins.
The 74AHCT32 has very simple wiring (IMHO), but many people use the 74AHCT125.
Fun fact - for WLEd circuits. If you wire all your floating inputs to ground the 74AHCT32 can be just dropped in to replace the 74AHCT125, they’ll function identically.

OK, so I just checked all my parts storage drawers and YAY, I found a promising component that looks like a level shifter:
Could this be the part I need?
If yes, how should I wire it in?
EDIT:
Damn,
I just googled the part number and it looks similar to a level shifter, but it indeed is a shift register, so no luck with this…
Best regards

Looks like Divsys has you covered. I agree with Divsys.

Yah, that’s a Shift-Register so not the kind of logic that’ll work for WLED in this case.
The other issue is that’s the “74HC” series not “74HCT” , the missing “T” means TTL compatible which you want.
The other common part number used is 74AHCT245, an 8 bit address buffer.
Many of these things are available on Amazon, I’ve even used the SOIC vs the DIP versions with a SOIC to DIP adapter board. The adapter board gives you something to wire to if you’re putting this inline with your data.

OK, so I found some SN74AHCT125N on Amazon and bought them, should arrive tomorrow.
How should I wire it into my data line?
Check out the page I referenced before in the KB: Compatible Hardware
There’s a wiring diagram, although I personally don’t use the 62R-100R resistor.
