These are a good stand-in: https://www.aliexpress.com/item/1005002906547500.html
They are strip lights, but the light is mostly omnidirectional, and the strip material is flexible. If you want a dark-colored strip, which looks better on a dark-green tree, here's a non-BTF option: https://www.aliexpress.us/item/3256805412113378.html
I've had a set of these (purchased from Amazon) deployed since October and we've been happy with them. The outdoor strand is run by a QuinLED Dig-Uno board and has stood up to a lot of rain so far. The wires at the end are just flush cut short with the conductors showing, so I made some attempt to weatherproof that spot just in case.
The colours look decent, but like you said, the conductor appears out of place.
NOMA has a “smart” line of traditionally packaged lights, but these appear to use a proprietary box: https://www.canadiantire.ca/en/cat/christmas/christmas-light...
