Would you recommend a warm or cold white light, after having one for over two years? At the moment I only have 2 rgb led lightbulbs, which have less than 1k lumens each, so I'm thinking of getting more "white-only" bulbs for more lightning but I'm curious about the warmth of the light: I literally only always go below 2700k.

For a garage, a cold white light (higher color temperature) will give you more lumens per watt, so you'll see brighter light. If the CRI is high enough, then things won't look too weird and your eyes should adjust to what just looks to be a brighter and whiter light. A higher color temperature light is usually also okay or even recommended for kitchen and bathroom use, if the CRI is high enough. A warmer light (lower color temperature) is usually recommended for living rooms, bedrooms, and other places where you're going to be participating in more leisurely activities, or sleeping, etc.... Ideally, you'd have lights that can cover the gamut and switch from high color temperatures (whiter light) during the day, and lower color temperatures (warmer light) at night, and then you would be able to adjust in each location for the type of light that you like best and that seems to be best suited to the activity. There are some "white" lights that include LED modules with two or more color temperature set points, and allow you to adjust where you want things to be between them. But they are more expensive, and more difficult to find.

It depends on the use case. As the sibling says, you want both, ideally a gamut, depending on the use case. When I bought the light in my comment, I already had some Hue white lights, but they didn't make much of a difference during the day. Some pencil Osram lights [0] did help somewhat in the morning, so that's when I decided I should try a "serious" LED light. As this was for working during the day, I wanted a cooler light, but my experience with other "cool white" lights was that they looked too much like hospitals, so I settled somewhere in the middle. While I never tried to measure the temperature, it's definitely cooler than the Hues and Osrams, but I still find it pleasant.

I had grabbed those because there were two lamps with this socket in the apartment I was renting at the time.
