When I lost my technician job a few years ago, I took up a repair shop job to make ends meet. Basic Windows features (starting with 8 and going up to 10, can't speak for 11) were just completely broken on a lot of budget hardware. A little over a quarter of the non-hardware problems I fixed were SysMain and Defender deciding they deserve all system resources.
If you have hardware it 'likes', and you don't need to edit settings other than what they provide to you, you'll be fine with your use case. A ThinkPad probably would not have the issues I saw.
