How to cope with the Rising cost and Future Planning?

After 10 years of subscribing to Adobe Creative Cloud and using Lightroom only, I recently closed my subscription. I am a hobbyist and have a large catalogue of photos I used to access LR and edit about once a month, I rarely used photoshop. Sadly I cannot afford a new laptop and I wasn't able to update due to my legacy system. Additionally I'm not a fan of paying monthly and after the recent increase I panicked and closed my account. Although I can pay it now, retirement is looming and I need to consolidate my outgoings.

My question is - what, if any, are the alternatives? I was hoping I could still use the Lr catalogue to view but I have failed to get this working. Luckily my images are saved locally and could be re-catalogued. I do plan to upgrade my laptop at some point. I want to continue my favourite hobby but also plan for the future and find a way my children can still access their history once I am no longer here.

I would appreciate any suggestions and I'm interested in how people plan for the future of their photographic legacy.
