Ah damn, I just bought some TPU, I'll have to buy a regular nozzle for it.

Wanted to add, for your next nozzle if you plan on printing abrasive filaments like CF, GF or glow-in-the-dark, pick up either an Obxidian or Diamondback nozzle. Don't bother with high flow for these. It's just gets in the way. I love the Diamondbacks but they are expensive. The upside is they never (in theory) wear out.

Thanks!

Are there downsides to using a regular profile with a HF nozzle? The reverse situation I know there is.

I tried looking for differences between the HF and regular profiles, I couldn't find any. But I assume it's just a higher volumetric flow?

Yes, you can use a regular profile with a CHT nozzle, but not the other way around. The main difference is max volumetric flow.

You can print TPU with a CHT nozzle, it's just that TPU has to be printed slowly so a high flow nozzle offers no advantage and more importantly, TPU has a tendency to clog nozzles if you are not careful. Unclogging a CHT nozzle is not as easy unclogging a regular nozzle. For the CHT you have to do a cold pull to unclog it.

I just finished building my Core One+ last week, and I've been using the included nozzle (High-flow Prusa Nozzle brass CHT - 0.4 mm) and also the default print profile. Can I use the high flow profile or do I need to buy a different nozzle?

Which nozzles allow me to use the "high flow" profiles? Is it any nozzle called "high flow" and also the CHT nozzles?

Thanks in advance

CHT are high flow nozzles so you can use the high flow profiles with these. My advice is to pick up a “normal” flow nozzle for materials like TPU and if you plan to print anything with carbon or glass fiber, you will need a hardened nozzle for that. Also, for general purpose where I don’t care so much about detail (for example a purge bin) I’ll use either a 0.6 or 0.8mm nozzle.
