Bear in mind that the only "Random" potions are the ones that you get for free, and that they are determined when created.
So you can't guarantee a potion of Boldness from your free ones, but you do know what potions you have available to use after you create them. If you really want a potion of Boldness, you can see if you get one for free, and then just choose to make one with a 1st level slot if you didn't.
As 1st level spells, those potions are pretty good considering you can break the action economy a little. You can stack all those buffs with no concentration, and pass the potions to your party beforehand so they are taking the actions to "cast" them.
Possibly pretty solid for a character wanting more party support options rather than more personal power.
