Is this, say, <30MHz?
Yes, C0G will do fine, as well as PP film if you need somewhat bigger values anywhere. X7R, Y5P or even Z5U ceramics are fine for bypass or coupling capacitors, or electrolytics for much larger bypass.
SMT chips are desirable at higher frequencies, but if this thing isn't doing anything crazy or powerful, leaded should be fine.
Note that leaded MLCCs don't handle much voltage beyond their rating. Duh, I guess, but ceramic disc types can often survive many times their rating, a handy tip in a pinch, or when transients are expected.
(Which, heh, not like picking up distant lightning, more like nearby ESD or lightning-induced surge.)
