nonprofit vs. foundation structure

I would like to start a thrift store in Oregon.
I would like the profits to be a nonprofit that gave back to the community.
(501(c)(3) organization)

I was led to believe to incorporate as an LLC and get a 501(c)(3).
This organization would have a board
Was advised today that in 10 years if they wanted to change direction I would be a founder and not an owner/employee
I could not get any SBA loans only grants

Today I was advised to create the store as a for profit but have the donations go to the a 501(c)(3) foundation that I create. The items would be given to the foundation and the store would be paid for “processing”. 80/20
This organization would have an advisory board and I could continue to work at the store.
I would be able to have the store get SBA loans and the foundation grants.

The second is what I want but do not know there are any pitfalls.
Is there any different or tax reporting that I need to become familiar with? I know nothing about how this will affect financial, fundraising or insurance (but am researching furiously) and I just do not know where to turn.
Thank you for your time and consideration
