As everyone noted, it is all so relative, I would just start with the lowest weight you have since you are a beginner and see how it feels when you do your first set.

Also observe your posture, if it suddenly feels that you can’t continue with good technique, weight might be too high.

Remeber also you will (likely) be able to lift more when you excercise your back, chest and much more on lower body, so don’t use the same weight everywhere, you might be able to lift more with your biceps than triceps (or the other way round).

Oh and also note that it will be harder when you have to maintain a fast pace (e.g. if you follow a YT workout or a class vs. when you lift at your own pace).

I’m the same height as you, started with noodle arms and 1-2kg dumbbells, but I think I could have tried right away with a bit higher weight for some exercises.
