You might want to try RawTherapee. I have not used this software but it sounds good and it seems to be a more ethical option depending on your personal values.
It came up as a good alternative to Lightroom. Here is what RawTherapee says on their website:

It is cross-platform - you can use it on Linux, macOS, or Microsoft Windows. It is also international and available in over 15 languages!

It does sound like it does a lot more than you need but it sounds good. I think it might have a bit of a learning curve to it though.
