Apple Contacts software too bad to use now. Need recommendations for new contacts software.

Using macOS Big Sur 11.7.10.

Over the years Apple has cancelled the ability to sync Apple Contacts at home via a wire and mandated all Contacts syncing to go through iCloud. The result is iCloud updating that stops your ability to use the application and duplicate contacts. I'll list all the issues here looking for any help with them and ask for suggestions for a different contacts software that people are using that is working for them.

After Apple turned off personal at home wire syncing and made us all use iCloud many issues showed up.

iCloud immediate updates: Apple has programmed iCloud to update so quickly that if you change anything in a contact the server must be updated immediately and the "rainbow circle of death" shows up canceling any ability to use the app while the serve. This happens so often (I don't know the duration) that as soon as you change anything in a contact, you get the rainbow circle of death as Apple updates their iCloud servers and you can't type anything in Contacts as this nefarious update process occurs. Is there any workaround to this incessant update issue cancelling our ability to type while it happens.

Duplicate Contacts: I have up to seven duplicate contacts for each contact in my library now, not of my own doing. It will take me weeks to fix this. If I maintain just an iCloud database, there is always the danger of receiving, "do you want to maintain a copy on your computer" and the following deleting of all your contacts off your own computer if you select the wrong response. So I maintain a list of contacts associated with an email account AND my iCloud list. This has resulted in duplicating my contacts seven times. So I have to go in and edit each contact and delete all the duplicates for all of my 3000+ contacts. Any work around for this!

Drag and drop no longer works: If I update a contact, I can not drag and drop that contact into any group on the left. I have to quit Contacts and open it up again to enable drag and drop, which is annoying and time consuming.

All these issues have made it almost impossible to continue using Apples Contacts software. I don't see any easy fixes for this and I won't be updating my macOS until I buy a new MacBook Pro (when they get rid of the screen "notch" in ten years) so it looks like I'll need an outside software for my contacts going forward. Any suggestions would be appreciated for a software that:

Allows home syncing with a wire.

Does not duplicate contacts.

Does not disable drag and drop

Does not doable itself with server updates.

Thank you in advance.
