Here's a few tried and true tips for cabling..(also called eia/tia 568 standards)
Use solid Cat5e for horizontal runs from the patchpanel to the information outlet (jack). No longer than 90 meters.
Patch panel and information outlets should be catetory 5e rated as well.
Use stranded cabling for patch cables, no longer than 5 meters each.
Tips - don't try to make patch cables, especially with stranded wire. They require special RJ45 connectors and are prone to fail. Purchase all patch cables.
Good luck!
