Deciding between two job opportunities.

So I just finished my undergraduate career at a target university this week with a degree in Real Estate development/finance. I have two job offers on the table that I have to make a decision on by Monday. Option #1 is financial analyst position at Wells Fargo with their CRE lending team. They've got a great training program and have a massive deal flow across all asset types. Which I feel will help me truly learn each RE class type. Option #2 is my current internship position which will be turning into a full time offer. I'm an acquisition/development analyst for a investment company that builds, acquires, and manages self storage properties. I definitely like what I'm doing today and I like self storage, however I do feel there in a cap on growth because of how small the company is and I feel it's too early on in my career to specialize in any single asset type. The offers are as follows:

WF
$65,000 base salary
10-15% bonus
$5,000 sign on bonus
Full benefits

Current Job
$70,000 base salary
$15% bonus
$ Undisclosed Sign on bonus
Full benefits

My ultimate goal is to start building up my own portfolio and work on my own acquisitions/developments. I do feel that both help me achieve that goal in different regards but both do have their individual drawbacks. I'm looking at both opportunities from a 5-10 year lens and what each can do for my career opposed to the temporary benefits each has. Any advice would be greatly appreciated.
