Is my new build balanced or will it bottleneck?

Hi everyone,
I’m planning to upgrade soon and I’m not sure if this setup will be balanced enough:

• CPU: Intel i5-12400F
• GPU: RTX 3060 Ti
• RAM: 16GB DDR4 3200MHz
• Monitor: 1080p 144Hz

I’ve read about CPU/GPU bottlenecks but I’m a bit confused about how to check if this build will run smoothly. Some people say calculators are useful, others say benchmarks are better.
How do you usually check for bottlenecks? Do you just look at benchmarks or use some kind of tool?
Thanks in advance!
