Be careful about wiping it. You might have trouble getting it back to a usable state.

Even if you can reload a "clean" copy of High Sierra, you might not be able to

• Reinstall Pages – the version in the App Store requires Sonoma or later.
• Reinstall and use a purchased copy of Microsoft Office – due to Microsoft no longer supporting DRM activation of old versions of Office
• Install LibreOffice, without searching through the archive of old and unsupported versions to find a version that will run on High Sierra

I'd suggest making a bootable clone backup on an external USB drive, using Carbon Copy Cloner or SuperDuper!, and setting that aside, just in case you find yourself needing something to recover from.

Once you've done that – and migrated any data that you want to keep to a newer system – you may find it easier to simply delete files you don't need off the old MBP, rather than wiping it clean and starting all over from scratch. (Be careful with anything synchronized through iCloud. If you were synchronizing the old MBP to iCloud Photos, you'd want to turn off iCloud Photos BEFORE erasing photos so that you did not erase copies everywhere else.)

That way, you'll be trimming it down to whatever word processing applications you already have, that work, rather than wiping it down to nothing, then hoping you can get an OS and word processing applications installed again.
