What is the best companion for getting maximum carrying capacity? [duplicate]

If I only want to maximize my carrying capacity, what is the best companion to bring assuming I'm willing to take any necessary perks?

I'm not interested in having pocketed or +str equipped items on companions as it gets really messy with the "Take all" action.

Dogmeat works with the Lone Wanderer perk which gives you +100 capacity at rank 2. This already makes dogmeat look like a good candidate for best carrying capacity. However I don't actually know how much each companion is able to carry. In addition the 3rd rank in the Inspirational perk increases carrying capacity, but it doesn't say by how much. If it's an additive bonus this would initially not affect this question, however because Lone Wonderer works with dogmeat I'm unsure if Inspirational also works with dogmeat?

TLDR:

• What is the base carrying capacity (including base strength) for each companion?
• How does the Inspirational perk work, and does it work with dogmeat?
