You can craft it and it's very easy to do it: all you need is: a diamond, a block of lapis, 6 of cobblestone and 1 of mossy cobblestone.
After you crafted it hold it in your MAIN hand and right click. You'll be introduced to this GUI:

In this gui you can customize your guard's equipment, name and trait/variant.
Personal Guards can use shields, but if there are some modded enchantments they won't work (Some vanilla's enchantments won't work too). For Ranged weapons and consumables: long story short... no. I tried to do it in many ways but i really can't figure out how to check if an item is a projectile. I could make some of the throwable items in minecraft usable by the guards but i find it pretty useless. Or i could make a separate guard that shoots arrows, but that wouldn't be so appealing...if you get what i'm saying.
Conclusion
Thank you for your attention, and remeber that every suggestion will surely be taken in consideration. Have a good day!
