Table problem: linebreaks within cells that are vertically centered AND table spanning multiple pages

After having spent a while optimizing my first table to look acceptable, I ran into a problem when I needed the same thing again, but with the table also covering multiple pages. I found out about \longtable, but I can't use it as it is incompatible with my other requirements as far as I can tell. The problem with looking up answers is that I get solutions for each single problem, but I can't combine them to cover all my requirements.

required:

• uses LuaLaTex (I have to use Times New Roman)
• the table can stretch over multiple pages
• line breaks within table cells
• vertical centering of the text in each cell
• the different rows of the table have to be distinguishable (you need to be able to tell which table-row a word belogs to, even if it is in a cell with multiple lines)
• a label to be able to reference the table
• compatibility with \begin{landscape} \end{landscape}

things that I would highly appreciate, but that I could bear to live without if not possible otherwise:

• automatic line breaking (setting \linebreak manually instead)
• individual setting of the horizontal alignments for each column (one column left-justified, the other centered,...)
• no warnings about underfull \hbox-es

In the code example below I go through the evolution of my tables, to show you some of the problems I ran into and how I solved them. I found a solution I was very happy with, but it is incompatible with \longtable. This nullifies all the advances I have made in terms of linebreaks within cells, vertical centering and generally producing a respectable table.

Here is the code example:

\documentclass[a4paper,11pt]{report}

% preamble

% general: margins, font, spacing

\usepackage[twoside,margin=2.5cm,bindingoffset=1.25cm]{geometry}

\usepackage{fontspec} % for times new roman
\setmainfont{Times New Roman}

\usepackage{setspace} % for 1.5 line spacing

% references to papers, figures, tables, ...

%    \usepackage[style=IEEE,backend=biber]{biblatex}

\usepackage{refstyle} % for figure references

\usepackage{tabulary} % for easier handling of multiline entries in tables
\usepackage{array,booktabs} % http://ctan.org/pkg/

\usepackage{longtable} % for multi-page tables

\usepackage{lscape} % for horizontal tables

\begin{document}
\begin{onehalfspace} % line spacing

The following table is pretty bad. One entry/row is hard to distinguish from the other. Also, it produces four warnings for underfull hboxes. Everything is aligned to the left, which is not good, but there might be a solution for this which I didn't bother to look up due to the other problems.

\medskip

\begin{tabular}{p{7.5cm}p{2cm}p{3cm}}
\hline
\textbf{word} & \textbf{word} & \textbf{some text} \\ \hline
some even longer text, it \linebreak starts to get uncomfortable & some \linebreak more text & word \\
some text that is so long that it will have \linebreak to cover multiple lines no matter what & some \linebreak text & word \\
%\label{table:thefirstfailedattempt}
\end{tabular}

\bigskip
\bigskip

The following example is better, at least it doesn't generate warnings, decides where to include line breaks within cells and self-adjusts the width of each column. Moreover, it is easy to define the alignment for each column separately, which is something I appreciate. But the vertical centering is missing. This is not acceptable to me.

\medskip

\begin{tabulary}{14cm}{CCC} % good except for missing vertical centering
\hline
\textbf{word} & \textbf{word} & \textbf{some text} \\ \hline
some even longer text, it starts to get uncomfortable & some more text & word \\
some text that is so long that it will have to cover multiple lines no matter what & some text & word \\
%\label{table:thesecondfailedattempt}
\end{tabulary}

\bigskip
\bigskip

With this solution (Table\,\ref{table:solutionfound}) I was very happy. Distinguishable rows, vertical alignment, table-label and a nice format as the cherry on top. This is what I was looking for.

But then I reached the next table (Table\,\ref{table:thetablethatistoolong}), which is quite the monster. I had to switch to landscape to fit all the columns in, but I quickly found a solution that worked. However, it is too long and stretches over multiple pages. By looking up other stackexchange answers I found out that longtable is the solution for this. But my previous solution is not compatible with longtable, which nullifies all the advances I have made in terms of linebreaks within cells, vertical centering and generally producing a respectable table.
I could split this table into three separate tables (defined by the second column), but the third table (second column is 'bar') would still be too long for one page.
