Help identifying existing rough in plumbing in unfinished basement

Hi all - I am in the planning stage of finishing my basement and would appreciate some feedback on the plumbing.
I don’t have much experience (yet, still in my 20s!) with plumbing but I need to get an idea on how I can design and frame this bathroom with what is in place. Help on identifying which piping is meant to handle toilet/shower/sink would be awesome.

The pipe in the far right corner has an outside cap diameter of 4.5”. I couldn’t get the cap off to measure, looked bigger than 3” though. All the rest are 2” and 3”.

I’ll do my best answering all questions. Pictures to follow.

Help in identifying what their thought was when laying this out would be appreciated.

Is there anything stubbed out overhead that isn't pictured? (Vent pipes) Looks like a builder that did his own plumbing rather than hiring a professional.

The 3" pipe that runs up the wall to the right turns 90 and runs with the lvl beam, I'm almost positive there is nothing at the back wall.

I'm referring to the area above the two 2" pipes left of the paint cans and the single 4" pipe that us stubbed up by itself to the left of that.

Something might be up there but could be covered with insulation.

Left to Right (best guess at intended layout)

Large pipe against wall = Laundry (dryer & washer)
Small pipe by framed section = utility/laundry/soaking sink
Small pipe by framed section = water softener discharge
Large pipe set away from wall = toilet
Small pipe set away from wall = bathroom sink

And all those locations need to be vented up through the roof. I think the question is, is there a vent pipe in the joists that we cannot see that is intended to vent these new basement fixtures?

Vent update

Thanks for the responses, I would have replied yesterday but there was site maintenance.
Anyways - there is a vent pipe and water line stubbed out coming from the ceiling (pictured), I can run this pretty easily to the roughin locations. I have attached a sketch of what I would like to do, as well as a description below.

Left to Right

Large pipe against wall = Sink for wet bar
Small pipe by framed section = Shower drain
Small pipe by framed section = water softener discharge?? Shower drain?? Ideas are welcomed
Large pipe set away from wall = toilet
Small pipe set away from wall = bathroom sink

I don't see why the wet bar and shower drain wouldn't be compatible with what is there, but I don't have much, or any, experience with this.

Thanks again for your feedback.

Update - talked to the builder, the vent is not coming out of the ceiling. Description is below.

Left to Right

Large pipe against wall = Wet bar sink
Small pipe by framed section = shower drain or vent
Small pipe by framed section = shower drain or vent
Large pipe set away from wall = toilet
Small pipe set away from wall = bathroom sink

Does anyone have a reason that the 3" again the wall (far left) can not be made fitted for a sink drain?

Well, if you look at 1800s blue collar bars, they didn't make a distinction between "boot washing drain, urinal, spittoon, floor drain.. Yep, the rougher neighborhood bars had floor drains FACING THE customers....
