I am designing a prototype for a unit that may go into production (not for profit organization). For some of the parts, geometry will be important. I need a power jack, a two wire fan connector, a switch, and a 10K potentiometer. Obviously, I want to design the unit with the particular part geometries in mind and I want to ensure that any parts I use will remain available, or that equivalent parts from a different manufacturer will. There are standards on transistor packages, etc. Is there any standard for, say, potentiometers? Where can I browse these standards and pick a geometry that suits my application?

Many major electronics suppliers (Mouser, Digikey) have parametric searches, so you can specify, for example, what transistor package you're looking for, or what potentiometer shaft diameter or mounting type you want. If you're looking for the most flexibility (swapping/upgrading/adjusting parts as needed) I'd suggest the following;
Of course, I'm making a few assumptions (you'll be mounting things on some sort of chassis or panel, and by potentiometer you don't mean a trimmer) but again, feel free to specify your needs/intentions and we'll be happy to clarify. I realize I haven't exactly specified standards per se, but my aim was to show you some regularly available options.
