I would like to know how far before touchdown the landing gear is
typically deployed for larger commercial aircraft. Thanks.

On a standard ILS, landing gear is extended when the glideslope needle is a
half-dot above intercept. This prevents excessive pitch changes that might
occur if done at intercept. On a visual approach the gear is extended as
needed so long as we are in the landing configuration before 1000' AFE.
