In the future tense, is the second syllable in verbs such as "glanfaidh", mostly pronounced like "kaidh"? or, like "caithfidh" "kidh"?

Thanks

I don't see where your k sound comes from.

Normally the f of the future and conditional endings is pronounced as an h (in Ulster, Connachta and in most forms of Munster).

Glanfaidh > "glan-hee" (Ulster), "glan-higg" (Munster), "glan-huh" (Connachta), but before pronouns as mé, tú, sé, sí, muid, sibh, siad... -faidh and -fidh are always pronounced "huh".

Caithfidh > "kah-hee", "kah-higg" & "kah-huh" (as above).

go bhfeicfidh mé might sound as though there were a K in there

The h sound can be silent so there's no difference between feicfidh and feicidh.

H is always silent following b, bh, d, g, mh. But h devoices them to "p", "f", "t", "c", "f".

Further more:
In "fan go bhfeicfidh mé" it is likely that it is in fact "go bhfeicidh mé" or in Standard spelling "go bhfeice mé": It is present subjunctive rather than indicative future.

Yes, "h". Sorry, I need to slow down. Thanks much.

In the West, l, n, r and ng can be devoiced or partially devoiced too, ex: dúnha mé etc
