Keep in mind, you don't have to pick skills that align with your ability scores. If you are a low skill class, use your background and race to make up the difference and pick up skills that fill in the gaps rather than buff up your already excellent ability related skills.
e.g. If you are going to play a wizard, maybe go with a Guild Artisan High elf to pick up Perception, Insight, and Persuasion. The proficiency bonuses (starting at +2) will make up the difference between a 10 and a 14 in the ability scores, and will only increase as you level up.
