For a new to newish player, assuming absolutely no expansions or purchased things (Arti, FVS and Alchemist are not F2P) I would play the following.
For spellcasting, Wizard 18 / Rogue 2 - Palemaster for self healing, rogue for trapping and evasion. My go to 'I don't know what I wanna do but I wanna experience a bit of everything' build that's been tried and true for years now. Easy to understand, competent up through low or maybe even mid reapers if you build them right. Important: Take a level of Rogue as early as possible. If you're playing with friends, or are willing to put up with it, start level 1 rogue... you can't put points into Open Lock/Disable Device until you do that.
Feats (in vague order of importance): Maximize, Empower, Quicken, Insightful Reflexes, Single Weapon Fighting (just to get Heroic Durability improvements aka HP), Spell Focus: Necromancy (or Evocation).
Stats: Max Int, rest into con.
Skills: Open Lock (important, Disable Device (important), Balance (for Single Weapon Fighting), Spellcraft, Heal, Jump
If you have Warforged unlocked, you can go Warforged and self heal through Repair spells and drop Palemaster stuff, make sure to take the enhancement on Warforged that reduce to the chance for you to fail spells (warforged have a base 5% chance to fail spellcasts, but the enhancement to negate that is 2 enhancement points into the Warforged tree).
For melee, a pure 2h/Sword and Shield War Domain Cleric or Paladin - Both have self healing, enough support to get you through the game, and practically build themselves. The important thing to note is to choose a god that has a weapon you wanna use if you pick Cleric. I liked cleric, it was my first life ever and when I felt like I was having a hard time in a dungeon I could always fall back and play as a healer instead.
Feats (universal): Two Handed Fighting feats (or Shield Mastery), improved critical (weapon type you like using)
Feats (cleric): Quicken (always), Maximize, Empower (if you find yourself with extra feats after the above).
Feats (paladin): Improved Shield Bash (on sword and shield)
Stats: As high STR as possible, 14 INT, Rest into CON. You can opt to put some points out of STR for CON if you want, or some points into Wisdom for spellcasting on cleric (try to start with 16 STR, 16 CON and 14~ WIS and INT on a cleric).
Skills: Balance, Heal, Jump
For ranged, Arcane Archer is sick - Honestly has amazing AoE blasts from what I can tell, but I have less experience with this class so I can't comment too much. Almost plays like a warlock honestly, though. You have strong magical auto attacks and buttons you can push to make big explosions around an enemy you're targeting... and honestly, it might just be the way my brain is wired but DOTs make my brain happy and Elemental Inferno is sorta sick with it.
