With your budget and space limits, tbh start by filtering for weight and fold. Under 13 to 14 pounds and a single step fold you can do one handed will make stairs bearable. Then check infant fit and safety details such as a firm five point harness, deep recline, and brakes that hold firmly and release without a fight. Try a curb pop in a store if you can to feel whether the balance is stable rather than tippy, and roll it over a rough patch to see if the wheels track straight. If the fold feels natural and you can carry it for a minute without adjusting your grip, you have something that will work for daily park walks and small hallways. Trust your hands.
