You should be able to adjust the compressor to help that. Have you tried the “Compress Based On Peaks” setting?
There’s also “Limiter” and “Hard Limiter,” but I’m not sure which ones come with Audacity. Some of those tools are home baked.
If you want to commit to it, you can try Chris’s Compressor. Chris can simulate radio station sound compression, so no matter what you do, you don’t have to reach over and change the radio volume in your car. It does have a personality, so if you like it, you may have to do them all that way. I change the first value, Compression from 0.5 to 0.77 to get a louder, tighter sound.

Attached are some limiters and peak processors.
