2020 wrx 33k miles looking to upgrade performance

Hello all. I am new to the forum.

I have a 2020 wrx base model which I have driven 33k miles from new and I am now looking to up the performance. Currently the only mod is a Cobb big sf intake. I would like a bit more power, between 30-70hp more. For handling, I would like the setup to be good on secondary country roads which are uneven, off-camber, hilly with tight turns. So, something that can absorb bumps but remain composed. I am not looking for a stiffer suspension.

Any feedback is appreciated, especially if you have experience with specific products to consider and also products I should stay away from.
Thank you.
