With 12 Dexterity, you can invest in strength and get a bunch of strength weapons with low dexterity requirements
Or you can invest more in dexterity and get a different series of strength weapons that have 18 dexterity requirements
In terms of spells, you could invest into 18 faith later to use Blessed Weapon, a buff that augments physical damage, and some heal and force miracles
You can get a Composite bow quite early after you save a caged NPC in High Wall of Lothric tower, after finding the key a bit later, that bow scales with Strength and can help deal some ranged damage.
A good starting weapon either way is the Longsword and the Claymore, both of which you get in High Wall. It's ok to invest titanite early because you'll get plenty
If you want to keep dexterity low you can also get the Deep Battle Axe in High Wall, under the fire breathing wyvern. That is infused in a way that makes it do high damage but not dependant on stats, so it's very strong early, and then you can just un-infuse it into normal or infuse it with heavy (scales with strength)
