Selling items for 0.0004 Bitcoin.

[SFR10]

will buyers be prepared to purchase such a small amount?

Some of the items are domain names,

It depends on how good those domains are! I've knowingly overpaid for a few domains before ^{[I do know that doesn't automatically equate to "some of the fees exchanges charge for withdrawing the funds", but it was pretty close to the average ones]}.
I'd suggest focusing more on "how and where" to market them instead.

Do you think that in view of the current high price of Bitcoin, it is worth doing this over the regular blockchain, or should I open a lightning account?

There's a couple of things that you need to know before "opening a Lightning account".

You could use a custodial wallet like BlueWallet. This way, you would not have to worry about inbound liquidity and being online 24/7. If you decide to run your own node or use a non-custodial wallet, you will have to worry about inbound capacity - you will have to make room for incoming funds by spending some coins over the Lightning Network.

If you use a non-custodial wallet, you won't be able to receive any payments unless you keep your wallet open. The same applies to a node, but you would probably keep it online 24/7 anyway.

What’s up Jet, hope you are well my friend! As you know I’m a big collectibles guy and we buy/sell stuff for low amounts like that all the time. There are even some poker chips for sale right now for that exact price I do believe. Since you’re not in a huge rush, I say why not. Won’t cost too much right now.

0.0004 BTC its around  24.8-25$. this is not a too much price. people will bought your items with this price. But because of the too much transactions cost, people will refrain from it. Bitcoin withdrawal fees on Binance by Bitcoin Network is 0.0005 BTC. Which is higher then your items price. No one will cost extra 0.0005 btc To buy your items at price of 0.0004 btc.

In my opinion you can list some items for sell with fixt price of usd. And you can take payment via BNB, USDT, BUSD (by bsc Network)  Ltc (by Litecoin network) and any others crypto-currency by (Polygon network) Which will attract people to your items for the lowest transcation cost.

If he has some rare trading cards (e.g. Pokemon), I wouldn't mind the fees at all
