My recommendation for free Icon Sets that I have already used in many projects and like to come back to whenever a new project comes up.
Heroicons

Beautiful hand-crafted SVG icons, by the makers of Tailwind CSS.
Phosphor Icons

Phosphor is a flexible icon family for interfaces, diagrams, presentations — whatever, really.
Feather Icons
Simply beautiful open source icons.
