OpenOffice has seen essentially no development since 2011, when the trademark got transferred to Oracle after they bought Sun Microsystems.
The project got forked into LibreOffice to dodge the trademark issue, but it's the same devs, practically the same project, but now under a non-profit organization. Well, and with 14 more years of development.
So, use LibreOffice instead of OpenOffice. It will most likely come pre-installed on whichever Linux distro you go with. But you can also try it out on Windows beforehand, if you have concerns.
