How to manage wholesales, bundles, and order listing?

[TheGreenerGift]

I have the non-pro version of Shopify (my shop isn't big enough to afford pro, yet). Within that version, I'm wondering:

1. What do you recommend as a method for listing wholesale items that the retail consumer shouldn't be seeing, but make it possible for wholesale customers to shop online? I've seen suggested that we make a listing or collection that is password protected, but I haven't seen an option that's integrated into Shopify, and there's loadssss of apps, but I can't figure out which would serve this purpose well.

2. Do you have a method or app to recommend for bundles? Where customers can create their own bundle with their choice of variants within a few selected items? (For example, I want to do an eco starter bundle where they can choose 2 snack bags, 1 food wrap, and 2 bowl covers, but I want them to choose the fabrics. And then they get a small discount for buying the bundle instead of individual items.)

3. I used to organize the shop by themed drops, and now organize by product. Is there any case for me keeping the old listings archived instead of deleted? (They're from 2020-2021) I'd like to have my back end of the site much cleaner and less cluttered.

Thanks in advance for your help and insight! It's greatly appreciated! The message boards, google, and social media groups have been semi helpful for these questions, but haven't really yielded sufficient advice.

Thanks so much for the opportunity to ask you, direct at the source!
