I know the cool thing to do these days are shoot slugs and heavy pellets at 1000fps+ but I haven't been known to just go with the norm. Crazy take but I love shooting low powered PCPs. My newest acquisition was a gently used Uragan Compact .22. Came shooting 817fps with 16gr FX pellets. Nice speed but at that level the gun felt and sounded alittle harsh. But my plan was to back it down anyways for barn use. So I tuned it to 600fps with the same 16gr which put it at 640fps with the CPHPs for a nice 13fpe. It just sips air and is such a pleasure to shoot. The cocking effort is basically non existent and paired with a red dot makes a great 30yd and in gun. I did shoot a pigeon at around 45yds though yesterday with it and still easy to do with the red dot. For close range pesting in a backyard these are perfect power levels unless you deal with larger pests like a raccoon or something. I think if you haven't you should definitely try a low powered gun. You might love it.
