Star wiring or home run wiring or spider wiring (I like that descriptive word) seems best all around with DCS. One never knows what the future holds, one day you may want to feature DCS. So, because of that reason alone I "spider " wire all layouts. Of course each fed block is insulated from one another.
Another thing about star wiring that can be helpful, I have a toggle on every star feed for three reasons.
1.- For short detection on a larger layout one can shut down the entire pike then bring up each star run one at time so as to find the culprit.
2.- Most folks have at least a few conventional engines so the ability to shut down a district anywhere is an option.
3.- Storing an command engine on a dead track will not cause run a way time usage.
When using a modest loop or two a simple two wire connection is fine. Even on a small 2 wire feed loop, if you connect one wire at the twelve o'clock position and the other wire at the 6 o'clock position, conventional train speed will remain somewhat consistent.
Del City has decent wire pricing and they carry it in 12 colors. Multi colored wires help in busy panels:
