Project Open Source License

Question

open source

Dear colleagues.

Please help me solve the following problem.
At the moment I am writing a small project and I plan to make it open as soon as I bring it to a level that I will not be ashamed to present to the public.
However, the question becomes: under what license to lay out the source code.
I am not well versed in legal matters, so I ask for your advice.

I need a license that provides the following:

1. possibility of use in proprietorship projects;
2. inability to create a closed commercial version of my project with a closed source code;

I would appreciate advice on this matter.
Thank you for your attention.

About the Apache License:
> This license does not make the license to distribute the software unchanged, nor does it even insist that the software remain free and open source. The only condition imposed by the Apache license is to inform the recipient of the fact that you are using source code licensed under the Apache license.
In general, if maintaining open status by all forks is a necessary criterion, then you should look only at the GPL family. If the product implies proprietary linking, then LGPL, otherwise clean.
