Being 69 myself but with fingers of steel I would recommend the following

Don FIrth makes excellent suggestions concerning the classical guitar
You may want to relearn some voicings using Drop 2 and 3 chords as jazzers do
They do involve barres but have a bass note on the E or A mostly and upper strings for the rest of the chord There are very few barres and no full ones. I any case I would advise anyone using steel strings to use a capo or reharmonise their songs to avoid prolonged use of barre chords
