Help with 8 CHA Greatweapon Half-Orc Bard

A half-orc who's utterly at playing the flute and singing, but with bash your skull in with a maul.

Stats would go 17/14/16/8/10/8, take Great Weapon Master, go +1/+1 on STR and CON, take Resilient CON then max out STR and CON.

Obviously my picks should be spells like Sleep, Haste, Greater Invisibility, Foresight etc.

Unfortunately 22 spells plus 6 leaves me with a lot of space to get more spells and it's rather overwhelming.

Advice on spells, specifically level 1 spells after Sleep loses relevancy and Magical Secrets would be appriciated.

Bless is a good one to grab since your GWM.

Cloud of Daggers, firewall, wall of stone, half damage fireballs are still enough to kill a kobold. Raise dead, and some other healing spells. Fly, misty step, dimension door, leomund's tiny hut, comprehend languages.

Don’t remember if those are all bard spells or not.

For magical secrets I'm thinking Haste, Wall of Force, Contingency, Heal, Maze and Wish

Remember that Sleep can be cast with higher-level slots; it actually scales pretty well.

Stealing the hard work of others, I ran across this earlier which might be useful to you:

In terms of recommendations, Sleep, Longstrider, Speak with Animals, Heroism, Comphrend Languages and Unseen Servant all have their uses
