My rigs have barely changed in 30 years of fishing.
For bottom baits a basic simple knotless knotted rig with a line aligner.
For pop-ups a sliding ring on the hookshank stopped by a hook bead, and a coated braid hooklink stripped from the hook to the height I want the bait popped up. Either putty or a match anglers olivette is the counter weight.
This works with pop-ups and snowman baits.
Choose your hooklink material for the bottom you are fishing over. In weed I prefer braid as it lays better than stiffer materials like mono or fluorocarbon.
The running lead can be fished with a tight line or a slack line.
If there is no undertow, fish it with a slack line and your indicator fished at maximum drop only just providing weight. Whichever way the fish goes you will get a run, any bleep is notification of interest.
If you fish a running lead it is a Bolt rig, the fish will run, but can run towards you so you need your indicator tight.
