Hey!
I definitely wouldn't turn down a good job purely out of fear that it will hurt your TC applications (as it is unlikely to!). If anything, a legal recruiting role could give you some useful insight into the legal profession, law firms and the recruitment processes, and you will also be developing transferable skills that you can talk about in applications or interviews.
I would also be wary of holding out indefinitely for a paralegal role when the market is so competitive right now. If the recruiting job is at your ideal location, pays well, and gives you the flexibility to continue applying, it sounds like a pretty good option! You could always keep applying for paralegal roles alongside it if something comes up.
Ultimately, firms care much more about what you have actually done and what you have learned from it than whether your job title is "paralegal". I'd just make sure you continue getting some legal exposure where possible (e.g. open days, insight events, etc.) and use your recruiting experience to demonstrate relevant skills and commercial awareness.
Generally, having a job while reapplying is probably preferable to sitting around waiting for the ideal paralegal role. I would take the job if you like it and let the TC applications remain the priority alongside it
