I have found this series of problems to be a good way of getting started with a new language. Because they are straightforward, the main issue with the problem isn’t as much how you solve them, but how to get what I have in my head into a language I’m unfamiliar with.

They start off that way, so it is good for that, but that flips around in later problems... coding them is not the hard part. Many require nontrivial mathematical insight to solve in any practical time frame.

Makes me wonder if there's something like Project Euler but for more programming-like problems. Logic, application of well known algorithms, modelling, etc.

I really like Advent of Code for that. https://adventofcode.com/

There is cryptopals for crypographic security exploit stuff. It's very good!

Competitive programming sites are at least a lot more like that than PE.

Examples: cses.fi/problemset , codeforces.com , codechef.com , hackerrank.com (tho HR makes it harder to find the good problems every time I look).

Rosetta Code might fit the bill...

As long as you just read the problem description first, and don't cheat by skipping right to the implementations.

Stack exchange has their competitions, where, for example, you write a bot to compete against other bots, as well as code golf and things like "fastest solutions" to problems. I once wasted two weeks just reading the problems.

Also, CodeChef. https://www.codechef.com/

CodeWars?

LeetCode

That's exactly how I use them. After the first 50 or so the ROI of that diminishes and you need to move on to something more effective. For that I use a project that I keep re-doing in different languages / eco-systems (a simple spaced repetition learning application).
