I don’t think there is anything that compares to what you get with Lightroom. It’s really hard to compare to others because for $10 a month there is not a single program that give you all Lightroom does.
A partial list is:
Lightroom CLassicwhich is the version that resides in your computer
Lightroom CC which is the software that resides on your computer or mobile device for accessing Lightroom in the cloud.
Lightroom.com which is the browser based version that allows you to access Lightroom from any computer in the world
20 gigs of cloud storage
Adobe Portfolio which essentially is your own website or actually up to 5 different websites. With the ability to use your own URL if you want or your own domain name if you choose. All included in the price. This alone is worth more than $10 a month.
The other thing you get with lightroom is the available plugins. I don’t believe any other competitor has as many available plugins.
Plus you get Photoshop thrown in too. Not a lite version but the full version.

With all that said you didn’t really state why you are interested in an alternative and there are many valid reasons. The most often compared head to head would be Capture One. I would say Capture One is becoming an industry standard also. If you are just looking for a software that basicly does what Lightroom classic does that would be the closest

Let me make an observation that doesn’t directly answer your vacation. The common, well intended, suggestion to use free trials to guide your selection is a recipe for frustration. Thirty days is not sufficient to allow you to determine how one of these programs fits your needs. Lightroom is a poster child for this viewpoint. Its most important capability is management of your images with a data base. Accessing those capabilities are probably alien to your experience. Many people trip over that hurtle and dismiss not only LR but its teammate PS. You get both these days with the subscription.

Otherwise, I don’t think anything else is a better alternative.
