I have purchased from this Amazon seller several times and have not had a dud yet. The prices have come down drastically from last year and are quite reasonable.
Hmm I just got some from Amazon but they are the coin size ones. GreatestDeals (11x - 100x) NTAG215 NTAG 215 25mm NFC Stickers Works Great with TagMo (Android) and Placiibo (iOS)! Multiple Sizes Available! (50 Stickers) https://www.amazon.com/dp/B071ZZTT6T/ref=cm_sw_r_cp_api_glt_fabc_8JAV4HQ905HVMAX95DHP
Also have Amazon Prime but didn't find tags for prime.
Here's the one I bought. Bought on the 4th with other Prime-eligible items. Prime items came on the 7th, tags came yesterday on the 15th. I imagine it's a combo of covid-19 and AC hype, but I've had other packages delayed because of covid so I'm not too surprised. I'd just buy any listing sooner than later!
I use these and none have failed on me yet: https://www.amazon.com/gp/product/B071ZZTT6T/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 They're slightly smaller than my coins as well at 25mm
Edit: I don't even use it as a sticker, I just sandwich it inside and it fits snug and looks professional:
Not much help for you, but I just made a few tags a couple days ago (bought NFC Stickers on Amazon) and am not having any issues on the switch lite. Have the silver pokemon version.
We got the materials (NFC sticker, coin case, and coins) from Amazon. The picture of the animals we used was actually from a tumblr user except we photoshopped the background to the New Horizons leaf pattern.

put a NFC tag on that also, so people can tap to connect.
Mine have been spot on reliable. Maybe some iPhone models are better than others?

That's good to know about the shortcuts!
I was looking at this one: https://www.amazon.com/gp/product/B071ZZTT6T/ref=ox_sc_act_title_1?smid=A204R99Q3U43DD&th=1
In the questions, some people say that it can't be rewritten, even though it's an ntag215.
Try this, they are stickers but still coin size

this is the website of the mod on this sub reddit so it's a trusted seller and tags are pretty much guaranteed to work.
US based and have competitive prices; ships weekly on Wednesdays with < 5 day delivery. I use the NTAG215 Inkjet CR80 cards from them and like their quality. I also use non-Inkjet cards but those are a little pricier to work and print with.
~~These 25mm stickers also arrived in < 7 days domestic US as well.~~ N.B. listing is backordered, my regrets.

Hi. I posted here earlier letting you know about the NFC tags. To answer your question in your edit, I just wanted to share with you the ones I got on Amazon
You can use an app called tagmo and there is a guide to using it here. https://nerdburglars.net/wpamp/hardwareguide/faking-amiibos-using-an-android-phone
You might get in trouble if you download the bin file for the amiibo, like the guide says, but in terms of actual data, it's no different from a regular amiibo statue or card and your switch will not be able to tell the difference.
You will need an Android phone or any phone capable of writing to an NFC tag. There's also some sources on Reddit if you want more information. Good luck! Hope you get your ideal village!
