try a mod pack that way all the mods are there already for you so you do not have to worry about instaling them all also then add some more mods like the backpack mod etc
In the way of some Minecraft ideas I suggest watching someone else's videos and get inspiration on what they are building and put your own spin on it as that is what I do for my Minecraft videos.
This may be a little off-topic but what about making a Mod related collab with some other people who play minecraft and try out some various ideas a group?
