Is it best to form an LLC with Stripe (Delaware) or an LLC in your home state for a bootstrapped project?

Taxes on LLC's tend to be more straightforward since it's a pass-thru entity. And you can always file with the IRS as an S-Corp. Unless you're raising money, C-Corp is probably overkill.

Don't over complicate it. Just create an entity in your state. If you're raising money, you can set aside $5-10k and any competent lawyer can convert your LCC to a Delaware C-Corp.

C-Corp if you ever want to take on investors or sell to another company. You can start LLC but you'll need to switch to C Corp if you raise investors.
