What are you looking to gain by ditching STR? Your DEX could be 13 instead of 12, opening up some multiclass options that you probably don't care about, and you could get your INT and CHA modifiers up a bit, but is that worth it? You'd become completely dependent on shillelagh to use a weapon, since you don't get any finesse weapons beyond a dagger.
As far as choosing hill dwarf in general, yes, you can wear the heavy armor with no speed penalty, but your speed is still lower than a human (that doesn't dump STR), and the same as a wood elf that does (and they at least can get 14 DEX and CON, 13 INT (in case you wanted a level of wizard at some point for rituals, arcane recovery, and the shield spell) and access to some ranged and finesse weapons). You do get more HP as a dwarf, but your concentration saves will be worse than a vuman with war caster, or even a vuman with resilient CON who also gets their CON up to 16 (at the expense of STR going down to 13 instead of 14).
Edit: Realized a hill dwarf can get 13 INT for a potential wizard dip just as easily as a wood elf can so disregard that as a distinguishing factor.
All I was looking for was a single classed cleric who can use his WIS instead of any other stat for everything.
