Play whatever race or class interests you, especially if you're just doing solo PVE content. Redguard, Imperial, Orc, Khajiit, and Bosmer are some of the more stamina oriented races available, but you'd be fine if you didn't choose one of those. Class definitely doesn't matter if you aren't planning on doing endgame dungeons/trials/PVP, just choose what sounds fun.

Night blades are fab for solo stalking and ganking if you like the sneaky sort. Kahajiit are excellent for surprise critical damage.

Any class can be played as a stamina dps build since all classes has stamina abilities so I really can't recommend much. However, I have to say I have the easiest time levelling as a Stam Templar and also a Stam sorcerer.

A dk starts off hard to play but will pick up the pace at later stages. Really good with stamina weapons.

A Templar has really good sustain with self heals but lack certain aoe skills.

Night blade is my personal favourite but honestly requires to play differently in different stages of levelling due to certain abilities being available.

A stamina sorcerer has good skills but only picking up the pace at mid stages.

I like to play as a Dummer since it has both stamina and magicka racial passives but an argonian has good passives as well. A pure stamina race like nord, orc, red guard, bosmer and to a certain extend Imperial, are all good choices for stamina builds.

Hope this helps!

Basically do whatever you want for your first character, stick to some sort of theme or feel for a character.

Deal with min maxing later, it isn't even that expensive to redo a character.
