is it possible to make a server that has spigot plugins and forge mods? I know cauldron existed for 1.7.10, but I need this for 1.10+ Any suggestions?
I know there is such thing as a forge compatible spigot server. You could also look in to having mods developed to carry out plugin tasks.
Sponge is a great thing that allows to run plugins and mods, like bukkit / spigot and forge platform for servers. Chech it out here if you want. I'm not tried it but I don't know for bug issues, only for one and that is with the mod "FoamFix" which is optimization mod for RAM / CPU Usage (Minecraft Client & Server Side). I hope this to help you somehow.
