My question, do i need two panels?? One for constant power circuits and one for switched power circuts that only get power when key is on. The stock panel has both. The genaric Amazon fuse panel only has the constant power option.

Thanks

i'd say it's 💯 your choice. i think it's always good to have switched power at a fuse panel but you can certainly tap somewhere else

Do you already have the fuse panel? There are usually options out there for panels with split buses. Allowing one panel to do both.
Typical aftermarket ones are pretty large however, so there is that.
Are you increasing the number of fuses as well?

And there is a third circuit to keep in mind. The factory panel has constant power, switched power (with the ignition), and the one little tiny fuse that’s only activated with the headlight switch for the dash lights.

I do have the new one but it only has the constant power option. I will look for a dual mode one. I have added new circuits for stereo, lights, etc. For that little one i was going a fusable link.

If the one you have is truly little, and it's a size and shape you like and can work with, just get another one.
Then you can have one switched and one constant. Then deal with the dash illumination with a single inline fuse.

Post a link to what you bought, or pics of it (both sides).

Sizing a fusible link for new circuits takes a LOT of engineering, and it's not really effective for small loads (like >30A). It's much easier to size a breaker or fuse.

This shows a few ways to add circuits:
