If you are looking at top or free -mh then it's totally normal for "free" memory to be almost 0 and "buff/cache" to be close to total ram. Thats because Linux does a lot of resource caching in ram to improve performance. If an app needs more ram than is "free" then it gets it from "buff/cache".
The only column thats relevant when talking about ram utilization is "available" ram which = free + buff/cache, or just use moodeutl -m and it will conveniently show the % ram used based on these numbers.
Swap is only enabled to allow old Pi-Zeros to process in-place updates otherwise it's prolly never going to get used.
