Replacing inside 12v lights in older Roadtrek

[rstl99]

New to me 2001 Roadtrek has the original incandescent bulbs inside (and the original circular fluorescent lamp above the back table).
I suppose it's good practice now to replace to LED's, to save on some amperage draw on the house batteries.
I'm a bit mystified by the plethora of options on amazon, and have gone through a few youtube videos with no clear indication of what kind of LED I should put in there.
Hopefully some of you can guide me to a decent choice.

Basically two lamps in the Roadtrek (see photo). On the right is the 1141 automotive bulb found in all the lights except the ones above the dash and on each side at the top front, those are the 906 bulb on the left in the photo.

Any suggestions on decent LED replacements for both?

I assume I may be recommended to just replace the original light fixture above the back table (fluorescent) and go with an LED light?

THanks a lot.

p.s. I'm amazed at how stock is my Roadtrek's inside. People on youtube love to tinker with their interiors, upgrade this and that, but the PO's of mine seemed to have been content to just live with the stock setup.
