I want to install recessed lights in roof soffit. Can I use ordinary
indoor RL housing? The housing will essentially be inside the soffit,
not exposed to weather.

Your first consideration may be whether the building code permits
this (cf. the risk of fire in wiring exposed to atmospheric damp.) The
local agency for building permits can advise you.
