I just need to preserve some old data that I have on my computers, so I was wondering what would be the best way to archive stuff long term.

Blu-ray disks ? Multiple HDDs ? What do you guys suggest ?

Proficient in data archival, curation, compression and storage. Do these steps in order.

Curate data in tiers of priority for preservation. Organise.
Download appropriate offline software to ensure file format readability.
Compress videos. Survival of data is more important than 100% untouched bloated bitrate videos. HEVC @ CRF 23 VeryFast.
Deduplicate with Czkawka and https://github.com/0x90d/videoduplicatefinder
Use RAR with recovery record, or PAR to create redundancy records.
3-2-1 backup strategy with multiple HDDs. Buy Seagate IronWolfs with appropriate shockproof casing.
Verbatim 100GB Blu-Rays for the ultimate long term storage, with a spare Blu-Ray writer kept sealed in box away from dust, moisture and vibration for future. Store Blu-Rays in a fire/dust/water/vibration proof box with the Blu-Ray writer, can even survive in floods. It is the most optimal for cost and longevity, way more cost efficient than LTO-5 tapes.
