Oh, so just some smallish wire-to-board? There’s tons of things.
JST XH (2.5mm pitch) and clones is one of my favorites, as is the Molex KK 254 (2.54mm pitch) and clones (e.g. KF2510). These are readily available from both “reputable” sources like Digi-Key, as well as from aliexpess and eBay, and they’re contacts that aren’t horribly picky when it comes to the crimping tool. (Molex sells a tool for about $120, which is super cheap for a genuine tool.)
For wire-to-wire, the clone makers (but not JST itself!) sell wire mount XH connectors, and I know JST has some other series of connectors that have both board- and wire-mount male connectors. A wire-to-wire-only connector I like from JST is the SM series, commonly used for LED strips.
