I ended up using 2 90 degree sweeps and two inspection boxes (90's as well).
Used fish tape to pull nylon rope which was used to pull the wires.

Man, is it hard work. It's not a big job, but no come-along, just two
inexperienced guys huffing and puffing.

An inspection box is an asymmetric item. Pulling the wires into the box in
the longitudinal direction was relatively easy; feeding them back into the
"exit" that is 90 degrees to the body was problematic (especially the last 18
inches, or so). How does one do that last bit of wire so that you don't end
up with a twisted knot of wires that won't fit in the box?

It is easiest to start at a elbow fitting in the middle and feed wires
to one end. In any case, for the otherside of the elbow bunch the wires
so they remain in the same orientation to each other from the elbow to
the loose wire ends and feed the wire into the elbow in that
orientation. That prevents 'knots'.

Assuming an LB fitting where one entry to the elbow is out the back,
to pull the wires tight into the fitting, pull the wires out through the
back as the last step. As the wires get almost tight, pick the wire that
will wind up furthest back in the fitting and bend it at 90 degrees at
the location it will have when the wires are tight. Pull just that wire
out through the back until it is tight. Repeat for the remainng wire
that will be furthest back in the fitting.... If the back-entry of an
elbow connects to the back-entry of another elbow it is a real PITA.

If you had used all sweeps as John Ray suggested think of the fun you
would have avoided. Electricians have nifty motor drive wire pullers to
make pulls like this easy.
