After reading a few guides I have narrowed the options to the following.
1. Halfling using a Shield and Gnome Flickermace.
Halfling Luck at level 1 and at level 5 Cultural Adaptability for Gnome Weapon Familiarity. Heavy armor, A sturdy shield, and a 1 handed reach weapon to maybe trip enemies with should keep me alive. And a d8 weapon isn't that bad.
The strength penalty is a big downside in such a tight numbers system.
2. Dwarf using a Shield and Gnome Flickermace.
Unburdened Iron at first level and buy Full Plate asap. Adopted Ancestry as my level 3 general feat and Gnome Weapon Familiarity as my level 5 ancestry feat. I have to jump through more hoops this way but the stats are better.
3. Half-Elf using a Pick and Light Pick.
Half-Elf heritage (Elf Atavism for Cavern Elf)
Using Ravingrook's Duel Wield build.
Level 1 Double Slice
Level 2 Ranger Dedication
Level 4 Basic Hunter's Trick: Twin Takedown
Level 9 Rogue Dedication (via human Multi-talented feat)
Level 10 Agile Grace
Level 12 Sneak Attacker
Pick and Light Pick have the Deadly ability giving me more mileage out of crits.
Primary drawback to this build is no Shield means I take more damage.
