If I were to own firearms (which, of course, I do not, because they are DANGEROUS) I would select an AR-15 and a Glock 23.
Ar 15 with an Adams Arms piston kit tuned in and a CMMG .22lr conversion kit with four mags and 1000 rounds of Super subsonic in 60 grain for the .22 and 1000 rounds of 55 grain Soft point for the AR15, with at least six mags always loaded. Pistol should be a Sig P6 or P226 and a Ruger SR.22 is nice also, for light weight pocket carry around the house.
