A word on creating your first D&D character
Don’t pay too much attention to the online “guides” that tell you what race-class-background combination you should go for or the ones which tell you in minuscule detail what to definitely avoid. While some combinations are more popular and certainly go together very smoothly, like Half-Orc barbarians or Drow assassins, no race-class combination is an actual dealbreaker (at least in 5e) and you can go for whatever wild combinations you desire. In our current campaign we have a glorious gathering of homebrew races (my Thri-Kreen Fighter), homebrew classes (Half-Orc fistfighting berserker with a bloodrage), unusual race/class combinations the internet strongly advises against (Gnome Warlock), characters who talk their way out of situations and prefer asoiaf-style narratives (Human Noble character modeled after the likes of Petyr Baelish or Brynden Rivers), and dungeon crawler enthusiasts who just want to loot and level up (Human Sorcerer), who are all on different levels of experience (I’m the rookie and have only played a few months, while our DM has been playing for over 10 years and the others all rank somewhere inbetween the two) and all chose their characters for different reasons, ranging from the “Wouldn’t it be cool if…” sentence to one very puristic “This is my trusty character I’ve been playing in every campaign I ever did and I won’t ever play anything else”. Everything works. Talk with your DM, tell them about what you’d like to play or how you’d like to play and ask them to help you make it work. It will be possible. More often than not DMs like helping people create their characters, because it’ll help them get to know the new player and what they want from the game.
