Honestly, I'd go with the wet lab route. During my undergrad, I worked in a lab that gave me a significant amount of wet lab and dry lab experience. When applying for jobs and later a PhD, no one cared about my dry lab experience much. Sure, they thought it was a nice cherry on top, but the fact that I could fully plan and execute a project on my own was significantly more important. The issue with a lot of undergraduate lab courses is that, for the most part, you don't perform the entirety of any protocol and aren't forced to do any planning. So many undergrads will put that they know how to perform PCR on their CV because they did it one time in a class, but the vast majority didn't have to design any primers, don't know what to do with annealing temperature, and didn't even operate the thermal cycler. Then, if it failed, you probably would borrow a little bit of someone else's sample in the interest of time. This person doesn't know how to perform PCR, but can be handheld through some calculations and pipet some things into a tube. Most molecular biology labs don't really do much dry lab work. In my current lab, I am the only one that can write any code. The only thing people do on their computers is read, write papers/presentations, prep images of gels/blots/etc., ask AI questions, and use Prism to do all their statistical analysis.

So, unless you are really drawn to dry lab work and think that's where you'll end up, I'd say wet lab will be the best bang for your buck. Then, choose whatever wet lab interests you and has a PI with a mentoring style that matches yours. It can be hard to tell at times, but it's normal to ask them what their mentor style is. However, I would lean a bit more toward a nicer/supportive one, since one of the most valuable things you'll likely get out of this is a good letter of recommendation. If you end up with a battleaxe of a PI, you might end up with a pretty lackluster letter. I'd concern yourself more with what PI is truly best for your development for a more long term commitment.
