Hey @Shelly29646836ggc4. Welcome to the Lightroom Community. I'll help you get started with Import & Sync in the Lightroom Ecosystem.
We'll need more info. There isn't a definitive answer to your question yet; depending on what you want & what works for you, you can decide what Lightroom to start with.
One fundamental question that can help you decide is; Where do you want to store the full-size originals?
On the computer storage, locally? - Use Lightroom Classic; it stores the originals offline.
At the cloud, as a backup & available everywhere you go? - Use Lightroom desktop to import & sync the full-size images to the cloud at Lightroom web (https://lightroom.adobe.com)
You might have other questions & we've listed recommendations & answers to frequently asked questions here: https://helpx.adobe.com//lightroom-classic/kb/sync-faq.html
Give this a detailed read before you import or sync further. Let me know if you have any other questions.
Thanks!
Sameer K
