These are differences which matter. If you have to go to StackExchange for "entities 101" questions like this, that means your team is not performing properly.
"your team" means you, any staff, lawyer, CPA, tax advisor, etc. It is perfectly OK to have a CEO who doesn't understand this stuff, as long as the CEO relies on trusted advisors who do.
Why not just use Stack Exchange as your attorney etc.? Liability. If your attorney or CPA tells you to do X, Y and Z, and IRS later says "oh no no, X Y and Z were the wrong thing to do, here's $1000 in back tax, $100 in interest and $5000 in penalties", you show them the piece of paper where the licensed advisor told you to do that, and IRS goes "Oh. OK. Penalties waived".
If your team can't carry the weight, or if this grates against your personal style, then you should review why you selected an S-corp. in the first place. I think a passthrough Single Member LLC (SMLLC) would be a better fit, since the taxes are simpler -- IRS treats it as a disregarded entity, so errors like that won't matter to the IRS.
Of course, being sloppy with individual identity vs corporate will still hurt your liability shield, which is the thing most people get LLCs/corps for, so your team still has to watch that.
