HDR10+ backwards to HDR10

Yes, if your source has no max cll/fall values, you can leave them out.

It seams that x265 can determinate the encoding level based on the resolution of the video, framerate.

Yes, if you to not set level&profile x265 will guess them (hopefully not only on resolution and frame rate).

So my question is, should I use vbv or not? What is the benefit in using it or not?

You should since it guaranties that the output will be compatible to the selected level&profile.

Main 10@L4@Main

is okay, if the player you want to use support it (which is to be expected since it's a common level/profile/tier combination-)
