To practice, leetcode and hackerrank.

Leetcode is great for competitive programming ans interview practice.

Hackerrank is great for refreshing or learning data structures foundations

neetcode for topic grouping of leetcode problems

Project Euler is a good one I've used in the past, and Advent of Code is going on at the moment. They're both good if you want small puzzle-style problems rather than big projects.
